In figure half of the space between the plates of a parallel plate capacitor is filled with dielectric material of constant K. Then which of the plots are possible?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A, D
a.,d.
Suppose field in air gap is `E`. Then in dielectric it is `ElK`. For dielectric medium
`dV=-(E)/(K)dx` or `V=(E)/(K)x`
For air gap medium , `V=-Ex`.
