In Fig. 21-22, the particles have charges 91 = -92 = 201 nC and 93 = -94 = 142 nC, and distance a = 5.7 cm.
(a) Find the net electrostatic force on particle 3:
Fnet,3 = < 0.079 x
X > N
0.0231
(b) What is the vector sum of net electric forces acting on particle 1, 2, 3 and 4?
Fnet, 1 + Fnet, 2 + Fnet, 3 + Fnet,4 = < 0
