Question

For spherical symmetrical charge distribution, variation of electric potential with distance from centre is given in diagram. Given that $\, \, \, \, \, V=\frac{1}{4 \pi\varepsilon_0 R_0}\, for\, r \le R_0$ and $V=\frac{1}{4 \pi\varepsilon_0 R_0}\, for\, r \ge R_0$ Then, which option(s) are correct

• A. Total charge within $2 R_0$ is q
• B. Total electrostatic energy for $r \le R_0$ is zero
• C. At $r = R_0$ electric field is discontinuous
• D. There will be no charge anywhere except at $r = R_0$

Answer 1

Answer: (D)

There will be no charge anywhere except at $r = R_0$

Answer 2

The given graph is of charged conducting sphere of radius $R_0$ The whole charge q distributes on the surface of the sphere.
