Inside a parallel plate capacitor the electric field E varies with time as `t^2`. The variation of induced magnetic field with time is given by ......

A

`t^2`

B

no variation

C

`t^3`

D

t

Text Solution

Verified by Experts

The correct Answer is:
D
`E prop t^2`
`B=(dE)/(dt)`
`=d/(dt)(kt^2)` k is proportionally constant
=2kt
`therefore B prop t`
