The two plates `X` and `Y` of a parallel-plate capacitor of capacitacne `C` are given a charge of amount `Q` each. `X` is now joined to the positive terminal and `Y` to the negative terminal of a cell of emf `varepsilon=Q//C`.

A

Charge of amount `Q` will flow fromte positive terminal to the negative terminal of the cell through the capacitor.

B

The total charge on the plate `X` will be `2Q`

C

The total charge on the plate `Y` will be zero.

D

The cell will supply `Cvarepsilon^(2)` amont of energy.
