Shown in the figure is a shell made of a conductor. It has inner radius $\displaystyle a$ and outer radius b, and carries charge Q. At its centre
is a dipole $\displaystyle \overrightarrow{\mathrm{p}}$ as shown. In this case :
Official answer
(4)
electric field outside the shell is the same as that of a point charge at the centre of the shell
