    a)the forces between q1 and q3
    F = k * (q1 * q3/d13^2)
    k = (1/4πεo) = 9 * 10^9 Nm^2/C^2 and d13= 20 cm = 20 * 10^-2 m
    F=-1.125N
    b)the force between charges q1 and q3 is
    F1 = k * (q1 * q3/d13^2)
    = -1.125N
    the force between charges q1 and q2 is
    F2 = k * (q1 * q2/d12^2)
    =3.5N
