There is a solid sphere of radius ‘R’ having uniformly distributed charge. What is the relation between electric field ‘E’ (inside the sphere) and radius of sphere ‘R’ is

• A

  $\mathrm{E}\propto {\mathrm{R}}^{-2}$

• B

  $\mathrm{E}\propto {\mathrm{R}}^{-1}$

• C

  $\mathrm{E}\propto \frac{1}{{\mathrm{R}}^3}$

• D

  $\mathrm{E}\propto {\mathrm{R}}^2$
