    Answer:

    1438.4 N

    Explanation:

    Applying,

    F = kqq’/r²………………. Equation 1

    Where F = Electrostatic force on the balloons, k = coulomb’s constant, q = charge on the first balloon, q’ = charge on the second balloon, r = distance between the two ballons.

    From the question,

    Given: q = q’ = 4.0×10⁻⁵ C, r = 0.1 m

    Constant: k = 8.99×10⁹ Nm²/C²

    Substitute these values into equation 1

    F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²

    F = 14.384/0.01

    F = 1438.4 N
