Question
what are the (a) magnitude (in N) and (b) direction (in o from x-axis in the counterclockwise direction) of the net electrostatic force on particle 4 due to the other three particles? All four particles are fixed in the xy plane, and q1 = -40.046 ? 10-19 C, q2 = +40.046 ? 10-19 C, q3 = +80.092 ? 10-19 C, q4 = +40.046 ? 10-19 C, ?1 = 38o, d1 = 6.10 cm, and d2 = d3 = 2.20 cm.
