Solve the question $4($i$)$

Let $\text{'}R\text{'}$ be the radius of the cylindrical region in which the magnetic field is assumed to exist. $\text{'}E\text{'}$

is the induced magnetic field due to the increasing magnetic field $B$ and the rate of increase is

$\frac{T}{sec}.$

i$.$ What is the magnitude of the electric field $\text{'}E\text{'}$ at radius $($a$)r=4cm$ and $($b$)R=7cm.,7$

ii$.$ Plot a graph showing the effect of distance from center $,$ and $r$: on the

electric field $\text{'}E\text{'}$ for the above circular conductor.
