    Solution:
    (A)
    Force due to charge on q2 by the charges q1 and q3 will be calculated by using Coulomb's law
    Coulomb's law is defined as

    Value of K is equal to 1/40
    where o is permittivity of free space .Its volume is 8.85 x 10-12 c2/Nm2.
    Thus in S.I. system numerical value of K is 8.98755 x 109 Nm2c-2.

    For q1 charge
    Distance between two charges is given in the figure which is r = 0.5 m
    Here q1 = 5*10-6C
    q2 = -2*10-6C
    F1 = 8.98755 * 109 *(5*10-6)* (-2*10-6)/ (0.5)2
    = - 0.3595 N
    For q3 charge
    Force due to charge q3 on q2
    F2 = 8.98755 * 109 *(5*10-6)* (-2*10-6)/ (0.5)2
    = -0.3595 ...
