The electrostatic potential \( \left(\phi_{\mathrm{r}}\right) \) of a spherical symmetric system, kept at origin, is shown in the adjacent figure, and given as
\[
\begin{array}{l}
\phi_{\mathrm{r}}=\frac{\mathrm{q}}{4 \pi \epsilon_{\mathrm{o}} \mathrm{r}} \quad\left(\mathrm{r} \geq \mathrm{R}_{\mathrm{o}}\right) \\
\phi_{\mathrm{r}}=\frac{\mathrm{q}}{4 \pi \in_{\mathrm{o}} \mathrm{R}_{\mathrm{o}}}\left(\mathrm{r} \leq \mathrm{R}_{\mathrm{o}}\right)
\end{array}
\]
\( P \)
W
Which of the following option(s) is/are correct?
(A) For spherical region \( r \leq R_{o} \), total electrostatic energy store is zero.
- (B) Within \( r=2 \mathrm{R}_{0} \), total charge is \( \mathrm{q} \).
(C) There will be no charge anywhere except at \( r=R_{0} \).
(D) Electric field is discontinuous at \( \mathrm{r}=\mathrm{R}_{\mathrm{o}} \).
