Positive plate of the capacitor

Assignment Help Physics
Reference no: EM131242064

A parallel-plate capacitor with plates of area 420 cm2 is charged to a potential difference V and is then disconnected from the voltage source. When the plates are moved 0.4 cm farther apart, the voltage between the plates increases by 100 V.

What is the charge Q on the positive plate of the capacitor?
