A metallic rod is placed in a uniform electric field. Select the correct option.
Inside the rod there will be an induced electric field from $B$ to $A.$
Free electrons will accumulate at the end $B$ of the rod.
The potential of the end $A$ will be more than that at $B.$
The electric field outside the rod will not change due to the induced charged in the rod.
Two concentric hollow conducting spheres of radius $r$ and $R$ are shown. The charge on outer shell is $Q$. What charge should be given to inner sphere so that the potential at any point $P$ outside the outer sphere is zero?
Write important results regarding electrostatic of conductors.
For the situation shown in the figure below, mark out the correct statement
Figure shows three concentric metallic spherical shells. The outermost shell has charge $q_2$, the inner most shell has charge $q_1$, and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell is
If a solid and a hollow conducting sphere have same radius then
