Vedclass · Answer

(C) When a conductor is placed in an external uniform electric field,the free electrons within the conductor redistribute themselves until the internal electric field becomes zero.For any conductor,the induced surface charge density $\sigma$ is given by $\sigma = \epsilon_0 E_n$,where $E_n$ is the component of the external electric field normal to the surface.Since both conductors have the same shape and size and are placed in the same uniform electric field,the external field $E$ at the surface is identical for both.Therefore,the total induced charge $q = \int \sigma dA$ will be the same for both the copper and the aluminium conductors,regardless of their material conductivity,as long as they are both conductors.

Two conductors of the same shape and size,one of copper and the other of aluminium (which is less conducting),are placed in a uniform electric field. What can be said about the charge induced in the aluminium conductor?
