What happens if two small positively charged particles of equal magnitude are placed close to each other? a) the particles will experience a repulsive force but remain stationary. b) the particles will experience an attractive force causing them to meet. c) the particles will experience a repulsive force that will drive them apart along the line joining their centers. d) the particles will experience a force that will cause them to move in a circular path of uniform motion with fixed distance of separation.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
