Edit MetaData
A spherical metal shall A of radius $$R_A$$ and a solid metal sphere B of radius $$R_B(< R_A)$$ are kept far apart and each is given charge '+Q'. Now they are connected by a thin metal wire. Then-
$$E_{A}^{inside} = 0$$
$$Q_A > Q_B$$
$$\frac{\sigma_A}{\sigma_B} = \frac{R_B}{R_A}$$
$$E_{A}^{on surface} < E_{B}^{on surface}$$
