Question
A parallel plate capacitor with a dielectric of dielectric constant K between the plates has a capacity C and is charged to a potential V volts. The dielectric slab is slowly removed from between the plates and then reinserted. The net work done by the system in this process is
Options
A.1/2(K - 1)CV2
B.CV2(K - 1)K
C.(K - 1)CV2
D.zero
Solution
In both cases work done by the external force is same but opposite in direction
