MCQ
Shown in the figure is a shell made of a conductor. It has inner radius $a$ and outer radius $b$, and carries charge $Q$. At its centre is a dipole $\vec P$ as shown. In this case
- ASurface charge density on the inner surface of the shell is zero everywhere
- ✓Electric field outside the shell is the same as that of a point charge at the centre of the shell
- CSurface charge density on the inner surface is uniform and equal to $\frac{{\left( {Q/2} \right)}}{{4\pi {a^2}}}$
- DSurface charge density on the outer surface depends on $\left| {\vec P} \right|$
