here,
charge A , qA = 1.75 uC = 1.75 * 10^-6 C is at x1 = 11.5 cm = 0.115 m
charge B , qB = - 9.38 uC = - 9.38 * 10^-6 C is at x2 = 0 cm = 0 m
charge C , qC = 3.7 uC = 3.7 * 10^-6 C is at x3 = - 9.3 cm = - 0.093 m
a)
the net force on charge A , Fa = K * qA * qC /(x1 - x3)^2 - K * qA * qB /(x1^2)
Fa = 9 * 10^9 * 1.75 * 10^-6 * 10^-6 * ( 3.7 /(0.115 + 0.093)^2 - 9.38/0.115^2) N
Fa = - 9.82 N
the net force on charge A is 9.82 N in -ve x direction
b)
the net force on charge B , Fb = K * qA * qB /(x1)^2 - K * qC * qB /(x3^2)
Fb = 9 * 10^9 * 9.38 * 10^-6 * 10^-6 * ( 1.75 /(0.115)^2 - 3.7 /0.115^2) N
Fb = - 12.44 N
the net force on charge B is 12.44 N in -ve x direction
c)
the net force on charge C , Fc = K * qA * qC /(x1 - x3)^2 - K * qC * qB /(x3^2)
Fc = 9 * 10^9 * 3.7 * 10^-6 * 10^-6 * ( 1.75 /(0.115 + 0.093)^2 - 9.38/0.093^2) N
Fc = - 34.8 N
the net force on charge C is 34.8 N in -ve x direction
