Physics - Electrostatics Question with Solution | TestHub

Charges Q each are distributed uniformly on a nonconducting hemispherical shell (on the surface) and in the volume of a nonconducting solid hemisphere. A point charge is brought at the centre ${\mathrm{C}}_1$ of shell and at the centre ${\mathrm{C}}_2$ of solid hemisphere from infinity. If work done in these process are ${\mathrm{W}}_1$ and ${\mathrm{W}}_2$ then ${\mathrm{W}}_1/{\mathrm{W}}_2$ is equal $\mathrm{n}/3$. Find n .
