The plates of a parallel plate capacitor of capacity `50 mu C` are charged to a potential of `100` volts and then separated from each other so that the distance between then is doubled. How much is the energy spent in doing so

A parallel plate capacitor of capacity 100 mu F is charged by a battery of 50 V. The battery remains connected and if the plates of the capacitor are separated so that the distance between them becomes double the original distance, the additional energy given by the battery to the capacitor in joule is

A parallel plate capacitor of capacitty 100 mu F is charged by a battery at 50 volts. The battery remains connected and if the plates of the capacitor are separated so that the distance between them is halved the original distance, the additional energy gives by the battery to the capacitor in Joules is .....

An air capacitor of capacity 50 mu F is charged to a potential of 200 V. The area of each plate is 20 cm^2 and the distance of separation between the plates is 0.1 mm, find the energy per unit volume of the electric field between the plates of the capacitor .

The force between the plates of a parallel plate capacitor of capacitance C and distance of separation of the plates d with a potential difference V between the plates, is.
