Force between two point charges is equal to
F = Kq1q2 /r2
r = distance between them
so, both charges exert the same but opposite forces on one another
magnitude is equal but direction is opp

Two point charges Q_1 and Q_2 have opposite charges of 100 nano Coulombs. Q_1 is located at (-2, 5.0) and Q_2 is located at (1, 1, -squareroot 11). Find, R_21 |R_21| a_21 The force between them (Q_1 and Q_2)and describe the direction If Q_2 is moved to a new location (1, 1, squareroot 24) what is the work required on Q_2?
Now the charges Q_1 = 1.90.10^-6 C and Q_2 = -2.84.10^-6 C are fixed at their positions, distance 0.301 m apart, and the charge Q_3 = 3.03.10^-6 C moved along the straight line. For what position of Q_3 relative to Q_1 is the net force on Q_3 due to Q_1 and Q_2 zero? Use the plus sign for Q_3 to the right of Q_1. Write down an expression for the force on the third charge with the distance from the...
