You should think about why the energy is more negative in the second case. Hint: the two cases differ only in the locations of the leftmost two charges. Potential energy in a 1-D crystal Suppose the array has been built inward from the left that is, from negative infinity as far as a particular negative ion. Evidently the sum in parentheses above is just ln 2, or 0. Note that this is an exact result; it does not assume that a is small. The result is negative, which means that it requires energy to move the ions away from each other. This makes sense, because the two nearest neighbors are of the opposite sign. If the signs of all the ions were the same instead of alternating , then the sum in Eq. It would take an infinite amount of energy to assemble such a chain. Consider an edge that has two protons at its ends you can quickly show that at least one such edge must exist. There are two options for where the third proton is. It can be at one of the two vertices such that the triangle formed by the three protons is a face of the octahedron.

Or it can be at one of the other two vertices. These two possibilities are shown in Fig. click here to download An alternative solution is to compute the potential energy of a given ion due to the full infinite in both directions chain. This is essentially the same calculation as above, except with a factor of 2 due to the ions on each side of the given one. If we then sum over all ions or a very large number N to find the total energy of the chain, we have counted each pair twice. So in finding the potential energy per ion, we must divide by 2 along with N. The factors of 2 and N cancel, and we arrive at the above result. Potential energy in a 3-D crystal The solution is the same as the solution to Problem 1.

In Fig. which agrees with Eq. This result is negative, which means that it requires energy to move the ions away from each other. This makes sense, because the six nearest neighbors are of the opposite sign. W is probably going to be positive, because the four nearest neighbors are all of the opposite sign. Three different groups of charges are circled. The full chessboard consists of four of the horizontal group, four of the diagonal group, and eight of the triangular group. For larger arrays we can use a Mathematica program to calculate W. click here to download This program involves dividing the chessboard into the regions shown in Fig. If you want, you can reduce the computing time by about a factor of 2 by dividing the chessboard as we did in Fig. The W for an infinite chessboard is apparently roughly equal to 1. The prefactor here is double the 0. Zero field? The setup is shown in Fig.

We want the leftward Ex from the two middle charges to cancel the rightward Ex from the two outer charges. where the second factor on each side of the equation comes from the act of taking the horizontal component. For small y, the field points leftward, because the two middle charges dominate. But for large y, the field points rightward, because the two outer charges dominate. So the x component of the field due to the outer charges is 3 times as large, all other things being equal. Therefore, by continuity, there must exist a point on the y axis where Ex equals zero. and the tangential field in the opposite direction at one q due to the other q is q cos 2θ. Field from a semicircle Choose the semicircle to be the top half of a circle with radius R centered at the origin.

So the diameter of the semicircle lies along the x axis. Let the angle θ be measured relative to the positive x axis. The x components of the field contributions from the various pieces will cancel in pairs, so only the y component survives, which brings in a factor of sin θ. where the minus sign indicates that the field points downward if Q is positive. a Label the points on the curve by their distance r from the origin, and by the angle θ that the line of this distance subtends with the y axis, as shown in Fig. Then a point charge q on the curve provides a y component of the electric field at the origin equal to q cos θ. We therefore have a family of curves indexed by a. Go explore. Video Audio icon An illustration of an audio speaker. Audio Software icon An illustration of a 3.

But despite working through each solution numerous times during the various stages of completion, there are bound to be errors. So please let me know if anything looks amiss. And please make sure they also agree to this. In addition to any comments you have on these solutions, I welcome any comments on the book in general. Electrostatics Solutions manual for Electricity and Magnetism, 3rd edition, E. Purcell, D. morin physics. edu Version 1, January So the mass of this 1 mm cube is 1. The number of atoms in the cube is therefore 6.

The repulsive force between two such cubes 1 m apart is therefore q2 kg m3 9. The above F is therefore equal to the weight of aircraft carriers. This is just another example of the fact that the electrostatic force is enormously larger than the gravitational force. Balancing the weight Let the desired distance be d. The non-infinitesimal size of this answer is indicative of the feebleness of the gravitational force compared with the electric force. It takes about 3. The difference in these distances accounts for a factor of only 1. click here to download 1. Repelling volley balls Consider one of the balls. The vertical component of the tension in the string must equal the gravitational force on the ball. And the horizontal component must equal the electric force. b To find the potential energy of the system, we must sum over all pairs of charges. in view of Eq. The result in Problem 1.

And consistent with Problem 1. The net force is therefore dropping terms of. This correctly has units of inverse seconds. Alternatively: We can find the potential energy of the charge q at position x, 0 , and then take the negative derivative to find the force. Equivalently, the force is the negative derivative of the potential energy, and the derivative of a constant is zero. in agreement with the force in Eq. By symmetry, the tension T is the same in all of the strings. Each of the two charges q is in equilibrium if the sum of the vertical components of the electrostatic. click here to download forces is equal and opposite to the sum of the vertical components of the tensions.

Q2 qQ. These all make intuitive sense. Alternatively: To solve the exercise by minimizing the electrostatic energy, note that the only variable terms in the sum-over-all-pairs expression for the energy are the ones involving the diagonals of the rhombus. The other four pairs involve the sides of the rhombus which are of fixed length. And we may assume the proton lies in the xy plane. For an arbitrary location of the proton in this plane, let the distances from the electrons be r1 and r2. In general, Eq. Assume that the proton lies to the right of the right electron. The ratio of this. click here to download distance to the distance between the electrons which is just 1 is therefore the golden ratio. There are therefore two solutions with all three charges on the same line. Work for an octahedron. There are 15 pairs of charges, namely the 12 edges and the 3 internal diagonals. Summing over these pairs gives the potential energy. Both of these results are negative.

This means that energy is released as the octahedron is assembled. Equivalently, it takes work to separate the charges out to infinity. You should think about why the energy is more negative in the second case. Hint: the two cases differ only in the locations of the leftmost two charges.
