In Figure (a) three positively charged particles are fixed on an x axis. Particles B and Care so close to each other that they can be considered to be at the same distance from particle A. The net force on particle A due to particles B and C is 3.69 × 10-23 N in the negative direction of the x axis. In Figure (b), 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 6.08 x 10-24 N in the negative direction of the x axis.
