Question

A capacitor of capacitance C is charged fully by connecting it to a battery of emf E. It is then disconnected from the battery. If the separation of plates of the capacitor is now doubled, how will the following change
1) charge stored by the capacitor.
2) field strength between the plates .
3) energy stored by the capacitor. Justify your answer in each case

Answer 1

capacitor 2 battery plates
