4 C

6 C

5 C

3 C

Text Solution

Verified by Experts

The correct answer is:

Initially, the capacitance of capacitor

Where, A is area of each plate and d is the separation between the plates.
After filling with dielectrics, we have two capacitors of capacitance.

and
Hence, their equivalent capacitance is

i.e. new capacitance will be six times the original.
