Choose the correct statement related to the potential of the shell in absence of $q_B$
- A
Potential of the outer surface is more than that of the inner surface because it is positively charged
- B
The potential of the outer surface is $\frac{{\sigma b}}{{{\varepsilon _0}}}$
- C
Both the surfaces have equal potential
- D
$B$ and $C$ both
