16. A cloud-chamber picture shows the track of an incident particle which makes a collision and is scattered through an angle 1. The track of the target particle makes an angle 2 with the direction of the incident particle. Assuming that the collision was elastic and that the target particle was initially at rest, find the ratio m1/m2 of the two masses. (Assume small velocities so that the classical expressions for energy and momentum may be used.)
