    If the charge q₁ is tripled  then the force between the charged becomes 3 times the original charge.

    Explanation:

    Given:

    Distance between the two charges = r

    The force between two charges is given by:

    F_1 = k\frac{q_1q_2}{r^2}

    If q₁ is tripled, then the force F becomes:

    F_2 = k\frac{(3q_1)Xq_2}{r^2}

    \frac{F_2}{F_1} = \frac{3q_1q_2}{r^2} X \frac{r^2}{q_1q_2}\\\\F_2 = 3F_1

    Therefore, if the charge q₁ is tripled  then the force between the charged becomes 3 times the original charge.
