    Answer:

    q=3.09 x 10^-7 C

    Explanation:

    According to Coulomb’s Law

    F=k q1 q2 / r^2

    Since q1= q2 ( Because charges are equal)

    therefore

    F=k q.q / r^2

    or

    F=k q^2/ r^2

    Now

    0.034 = 9 x 10^9 x q^2 / (0.16)^2

    or

    q^2 = 0.034 x 0.0256 / 9 x 10^ 9

    q^2 = 9.6 x 10^-14

    Taking square root

    q=3.09 x 10^-7 C
