    Answer:

    The new force between charges is 2 N.

    Explanation:

    It is given that, a 3 C charge and a 6 C charge feel 4 N of force between them.

    The force between charges is given by :

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

    r is distance between charges

    Original force is :

    4=\dfrac{k(3)(6)}{r^2}\ ....(1)

    If the 6 C is replaced  with a 3 C, new force between them is given by :

    F'=\dfrac{k(3)(3)}{r^2}\ ....(2)

    Dividing equation (1) and (2) we get :

    \dfrac{4}{F'}=\dfrac{2}{1}\\\\F'=2\ N

    So, the new force between charges is 2 N.
