A uniform but time varying magnetic fiel...

A uniform but time varying magnetic field `B=(2t^3+24t)T` is present in a cylindrical region of radius `R =2.5 cm` as shown in figure.

The variation of electric field at any instant as a function of distance measured from the centre of cylinder in first problem is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
From Eq. (i) of above problem we can se that
`Epropr`
i.e. `E-r` graph is a straight line passing through origin.
