SSM In crystals of the salt cesium chloride, cesium ions Cs + form the eight corners of a cube and a chlorine ion Cl − is at the cube’s center (Fig. 21-36). The edge length of the cube is 0.40 nm. The Cs + ions are each deficient by one electron (and thus each has a charge of + e ), and the Cl − ion has one excess electron (and thus has a charge of − e ). (a) What is the magnitude of the net electrostatic force exerted on the Cl − ion by the eight Cs + ions at the corners of the cube? (b) If one of the Cs + ions is missing, the crystal is said to have a defect; what is the magnitude of the net electrostatic force exerted on the Cl − ion by the seven remaining Cs + ions? Figure 21-36 Problem 35.

The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
