    Answer:

    New force = 9(initial force)

    Explanation:

    The force between two charges is given by :

    F=\dfrac{kq_1q_2}{r^2}

    Where

    d is the original distance

    Let d’ is the new distance such that, r’ = r/3

    New force,

    F'=\dfrac{kq_1q_2}{r'^2}\\\\F'=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\F'=9\times \dfrac{kq_1q_2}{r^2}\\\\F'=9F

    So, the new force becomes 9 times the initial force.
