    Static electricity is produced by rubbing to two objects. It is the friction between the two objects that generates attraction between the objects leading to charge transfer. It is due to this contribution of friction that static energy is also called frictional electricity.

    Electric Field is the region around a charge particle or object due to which another charge particle or object experience force.
    E = F/Q
    Unit of electric field: E = N/C
    As, unit of force is Newton (N)  and charge is Coulomb ( C),  So unit of electric field is N/C.
