    From the equation describing the Electric field strength of a charge


    We can deduce that the electric field strength is dependent on the force arcing on the magnitude of the charge.

    As the force increases the the electric field increases, also the electric field strength decreases with increasing charge.

    Hence the distance has no effect on the electric field strength. The magnitude remain as E
