MCQ
$IAn$ empty thick conducting shell of inner radius $a$ and outer radius $b$ is shown in figure.If it is observed that the inner face of the shell carries a uniform charge density $-\sigma$ and the surface carries a uniform charge density $ '\sigma '$
Choose the correct statement related to the potential of the shell in absence of $q_B$
- APotential of the outer surface is more than that of the inner surface because it is positively charged
- BThe potential of the outer surface is $\frac{{\sigma b}}{{{\varepsilon _0}}}$
- CBoth the surfaces have equal potential
- ✓$B$ and $C$ both
