Physics - Capacitor Question with Solution | TestHub

To measure capacitance of a conductor it is first charged to a potential ${\mathrm{V}}_0=1350\mathrm{V}$. It is then connected by a long conducting wire to a metal sphere of radius $\mathrm{r}=3\mathrm{cm}$. As a result the conductor potential drops to ${\mathrm{V}}_1=900\mathrm{V}$. Choose the correct option(s).
