Part A Capacitors C, = 10µF and C2 = 20µF are each charged to 22 V, then disconnected from the battery without changing the charge on the capacitor plates. The two capacitors are then connected in parallel, with the positive plate of C connected to the negative plate of C2 and vice versa. Afterward, what is the charge on each capacitor? Express your answer using two significant figures. Enter your answers numerically separated by a comma. ?

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.
