2 A parallel plate capacitor having plate area 20 cm and separation between the plates 1 00 mm is connected to a battery of 12 0 V The plates are pulled apart to increase the separation to 2 0 mm a Calculate the charge flown through the circuit during the process b How much energy is absorbed by the battery during the process c Calculate the stored energy in the electric field before and after the process d Using the expression for the force between the plates find the work done by the person pulling the plates apart e Show and justify that no heat is produced during this transfer of charge as the separation in
