In crystals of the salt cesium chloride, cesium ions Cs* form the eight corners of a cube and a chlorine ion CI is at the cube's center (see the figure). The edge length of the cube is L = 0.36 nm. The Cs* ions are each deficient by one electron (and thus each has a charge of +e), and the CI-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 CI' 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 CI ion by the seven remaining Cs* ions?
