18 In Fig. 21-29a, three positively charged particles are fixed on an x BC (a) axis. Particles B and C are so close to each other that they can be con- sidered to be at the same distance B. A from particle A. The net force on particle A due to particles B and C is 2.014 x 10-23 N in the negative direction of the x axis. In Fig. 21- 29b, particle B has been moved to the opposite side of A but is still at the same distance from it. The net force on A is now 2.877 x 10-24 N in the negative direction of the x axis.
