    The electric field is zero inside the metal sphere


    Gauss's law says: the net flow on any enclosed surface is equal to the value of the charge inside divided by the electrical permittivity

    E = Q / ε

    Where Q is thec charge into the surface.

    If we apply this to the metal sphere, all the charge is on the surface, so there is no charge inside, therefore, the electric field is zero
