A solid metal sphere of radius R having charge q is enclosed inside the concentric spherical shell of inner radius a and outer radius b as shown in the figure. The approximate variation electric field E &#8594; , as a function of distance r , from centre O , is given by:

Aicharya · Accepted Answer

In the above question, the variation of the electric field with $r$ , is,

$For \begin{matrix} 0 < r < R & E = 0, \end{matrix}$

$\begin{matrix} for R \leq r \leq a & E = \frac{k Q}{r^{2}} \end{matrix},$

$\begin{matrix} for a < r \leq b & E = 0 \end{matrix} & \begin{matrix} r > b & E = \frac{k Q}{r^{2}} \end{matrix}$ , so the correct graph is,
