Problem
A parallel-plate capacitor is charged and then the battery is disconnected. When its plates are brought closer together, then
(1) energy stored in the capacitor decreases
(2) the potential difference between the plates decreases
(3) the capacitance increases
(4) the electric field between the plates decreases
