The capacitance of a parallel plate capa...

The capacitance of a parallel plate capacitor is `C` when the region between the plate has air. This region is now filled with a dielectric slab of dielectric constant `k.` The capacitor is connected to a cell of `emfE`, and the slab is taken out

A

Charge `epsilon C_0(k-1)` flows through the cell

B

Energy `epsilon^2 C_0(k-1)` is absorbed by the cell

C

The energy stored in the capacitor is reduced by `epsilon^2 C_0(k-1)`

D

The external agent has to do `(1//2) epsilon^2 C_0 (k-1)` amount of work to take the slab out
