A parallel plate capacitor has the voltage applied to it doubled.Is the force between the plates attractive or repulsive,and what happens to the force between the plates when the voltage is doubled?
A) The force is attractive and it quadruples.
B) The force is attractive and it doubles.
C) The force is repulsive and it halves.
D) There is no force between the plates since the net charge is zero on the capacitor.

The force between the plates of a capacitor is attractive and is proportional to the square of the voltage. Doubling the voltage results in the force quadrupling.
