Question

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

This question has multiple correct options
A

charge flows through the cell

B

energy is absorbed by the cell

C

the energy stored in the capacitor is reduces by

D

the external agent has to do amount of work to take the slab out

Medium

Correct option is
A

charge flows through the cell

D

the external agent has to do amount of work to take the slab out

After inserting the dielectric the capacitance will be
The charge flow through the cell when the slab insert is
 The charge flow through the cell when the slab is taken out
Net charge flow through the cell
The amount of work for taking out slab is
