three point charges are located on the positive y-axis of a coordinate system.charge q1 = -2.09 nC is 2.05 m from the origin and charge q2 = +2.70 nC is 3.25 m from the origin, and the third charge q3 = -2.56 nC is located 5.03 m on the positive y-axis.the fourth charge q4 = -4.06 nC is 3.97 m on the negative y-axis.what is the total force exerted by these charges on charge q5 = -7.43 nC located at the origin.
do coulombs law, add. For each force, location determines the direction of force. so draw a diagram first.
