A parallel plate capacitor has plate `A` and separation `d` between the plates. The capacitor is connected to a battery of emf `V`. (a) find the charge on the capacitor. (b) the plate separation is decreases to `d//2`. Find the extra charge given by the battery to the positive plate. (c) work done in reducing separation between plates.
