1.A parallel-plate capacitor is fully charged and then disconnected from the battery. The plates
are then moved closer together, how does the charge on the plate change
it needs to be stated whether the charge on each plate increases, decreses or stays the same
C=Q/V, C=epsilon_0 * A/d
when the capacitor is disconnected, the charges cannot flow. So each one should stay the same, right? The solution for this exam problem that was on last years final says that it should increase. This doesn't make sense to me. Is the solution wrong, or am I wrong?
