Question

An ideal parallel plate capacitor is charged by connecting it to a battery. The battery is then removed so that charges may no longer enter onto or exit from the plates of the capacitor. There is nothing between the capacitor plates. As the plates are moved closer together, the magnitude of the electric field between them:_________
a. decreases
b. increases
c. remains the same

Answer 1

Answer:

c. remains the same

Explanation:

The capacitance of a capacitor is can be represented as;

C = Q/V

There will be no charge flow from the battery to the capacitor or vice versa if the battery is disconnected.

Due to energy conservation, the energy contained and stored in a capacitor will continue to retain and be the same, since an increase in capacitance reduces the voltage, resulting in the same final energy stored.
