Problem
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.
(1) If the charge of one of the particles is +q, what is the charge of the other?
(2) 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.
