An initially uncharged parallel plate capacitor of capacitance C is charged to potential V by a battery. The battery is then disconnected. Which statement is correct?
a. There is no charge on either plate of the capacitor. b. The capacitor can be discharged by grounding any one of its two plates. c. Charge is distributed evenly over both the inner and outer surfaces of the plates. d. The magnitude of the electric field outside the space between the plates is approximately zero. e. The capacitance increases when the distance between the plates increases.
Induction: Two uncharged metal spheres, #1 and #2, are mounted on insulating support rods. A third metal sphere, carrying a positive charge, is then placed near #2. Now a copper wire is momentarily connected between #1 and #2 and then removed. Finally, sphere #3 is removed. In this final state
A. spheres #1 and #2 are still uncharged. B. sphere #1 carries positive charge and #2 carries negative charge. C. sphere #1 carries negative charge and #2 carries positive charge. D. spheres #1 and #2 both carry positive charge. E. spheres #1 and #2 both carry negative charge.
Consider an object (object A) whose multiplicity is always 1, no matter how much energy you put into it. If you put a very large amount of energy into such an object, and place it into thermal contact with an Einstein solid (object B) having the same number of atoms but much less energy, what will happen?
A. Energy flows from A to B until A has very little energy. B. Energy flows from B to A until B has very little energy. C. Energy flows from A to B until both objects have the same energy. D. No energy will flow between A and B at all. E. Something else happens (describe).
