Neutral Particle A neutral particle is at rest in a uniform magnetic field B. At time t = 0 it decays into two charged particles, each of mass m.
(a) If the charge of one of the particles is q = +20 C, what is the charge of the other?
(b) The two particles move off in separate paths, both of which lie in the plane perpendicular to B. At a later time the particles collide. Express the time from decay until collision in terms of m, B, and q.
