Consider a spherical volume which has uniform charge density ρ from x = R to x = 2R. There is no charge from x = 0 to x = R and from x = 2R to infinity. The electric potential due to this charge.

Select all that apply

• Option A

  at x = 0 is 0

• Option B

  at $x=\frac{R}{2}$ is $\frac{3\rho R^2}{2\epsilon_{\omicron}}$

• Option C

  at $x=2R$ is $\frac{7\rho R^2}{6\epsilon_{\omicron}}$

• Option D

  at $x=\frac{3R}{2}$ is $\frac{8\rho R^2}{3\epsilon_{\omicron}}$
