If the dielectric constant of a substance is `K=4/3`, then the electric susceptibility `psi_(e)` is

A

`in0/3`

B

`3in_(0)`

C

`4/3in_(0)`

D

`3/4in_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A
Susceptibility, `psi_(e)=(K-1)in_(0)`
`K=4/3` (given)
`psi_(e)=(4/3-1)in_(0)=(in_(0))/(3)`

In a parallel plate capacitor the separation between plates is 3 x. This separation is filled by two layers of dielectrics, in which on layer has thickness x and dielectric constant 3k , the other layer is of thickness 2x and dielectric constant 5 k . It the plates of the capacitor are connected to a battery , then the ratio of potential difference across the dielectric layers is
