Three point charges lie along a straight line as shown in Figure P23.12, where q1 5 6.00 mC q1 =
q2 5 1.50 mC,q2 =
and q3 5 22.00 mC q3 =
. The separation distances are d1 5 3.00 cm d1 =
and d2 5 2.00 cm d2 =
. Calculate the magnitude and direction of the net electric force on (a) q1, (b) q2, and (c) q3.
