Electric Potential Energy (An lonic Crystal) 3. Four positive and four negative charges of equal magnitudes +Q are arranged alternately on the corners of a cube of side length d, +Q as drawn. This is a model of one cell of an ionic crystal such as -Q +Q salt, NaCl. a. Calculate the potential energy of this configuration. As d usual, take the energy to be zero infinitely far away from the charges. Express the energy in terms of k, Q, and d. d Hints: -Q +Q There are 12 pairs of opposite charges along the edges There are 12 pairs of like charges along the diagonals of each face There are 4 pairs of opposite charges along the cube's long diagonals b. In part (a), you should have determined that U < 0. Explain the relationship between this result and the observation that such crystals freely form in nature.
