Q.
Which one of the following graphs represents the variation of electric field with distance $r$ from the center of a charged spherical conductor of radius $R$?
Electric field due to a hollow spherical conductor is governed by the following equation
$E=0$ for $r< R \ldots$ (i)
and $E=\frac{Q}{4 \pi \varepsilon_{0} r^{2}}$ for $r \geq R$
ie, inside the conductor field will be zero and outside the conductor field will vary according to $E \propto \frac{1}{r^{2}}$
