    Answer:

    E = 12.25 x 10³ N/C = 12.25 KN/C

    Explanation:

    In order to balance the weight of the object the electrostatic force due to the electric field must be equal to the weight of the body or charge. Therefore,

    Electrostatic Force = Weight

    E q = mg

    where,

    E = Electric Field = ?

    m = Mass of the Charge = 5 x 10⁻³ kg

    g = acceleration due to gravity = 9.8 m/s²

    q = magnitude of charge = 4 μC = 4 x 10⁻⁶ C

    Therefore,

    E(4 x 10⁻⁶ C) = (5 x 10⁻³ kg)(9.8 m/s²)

    E = 0.049 N/4 x 10⁻⁶ C

    E = 12.25 x 10³ N/C = 12.25 KN/C
