A parallel plate capacitor of capacitance C0 is charged using a battery of emf V0 . Calculate the work done by external agent in reducing the separation between the plates to half its original value if

In which case is more work done? The plates of a plane capacitor are drawn apart keeping them connected to a bettery. Next the same plates are drawn apart from the same initial condition keeping the battery disconnected
