Question

MESSAGE MY INSTRUCTOR FULL SCREEN PRINTER VERSION BACK NEXT apter 21, Problem 035 crystals of the salt cesium chloride, cesium ions Cst form the eight corners of a cube and a chlorine ion Cl- is at the cube's center (see the figure). The edge gth of the cube is L = 0.35 nm. The Cs+ ions are each deficient by one electron (and thus each has a charge of +e), and the clion has one excess electron d thus has a charge of -e). (a) What is the magnitude of the net electrostatic force exerted on the cl ion by the eight Cst ions at the corners of the cube? 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 naining Cs+ ions? Number o Units This answer has no units Number Units the tolerance is +/-5%
