Question:

A parallel-plate capacitor with plate area 3.0 cm2 and air-gap separation 0.50 mm is connected to a 12-V battery, and fully charged. The battery is then disconnected.

(a) What is the charge on the capacitor?

(b) The plates are now pulled to a separation of 0.75 mm. What is the charge on the capacitor now?

(d) How much work was required to pull the plates to their new separation?
