    Answer:

    The electric force between them is 878.9 N

    Explanation:

    Given:

    Identical charge q = -6.25 \times 10^{-6}C

    Separation between two charges r = 0.02 m

    For finding the electrical force,

    According to the coulomb’s law

       F = \frac{k q^{2} }{r^{2} }

    Here, force between two balloons are repulsive because both charges are same.

    Where k = 9 \times 10^{9}

       F = \frac{9 \times 10^{9} \times (-6.25 \times 10^{-6} )^{2} }{4 \times 10^{-4} }

       F = 878.9 N

    Therefore, the electric force between them is 878.9 N
