- Three particles, each of mass ‘m' and carrying a charge q each, are suspended from a common point by insulating massless strings, each of length 'L'. If the particles are in equilibrium and are located at the corners of an equilateral triangle of side 'a', calculate the charge q on each particle. Assume L >> a.arrow_forward18 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.
