I can't really try, seeing as I'm completely befuddled. The proton's angular momentum in respect to any point in space isn't constant, because there's an outside bloody force. Trying to use collisions of spherical objects might work, but there's no real R of the nucleus or the proton...Do you...
Homework Statement
A proton is shot horizontally at a nucleus on a cartesian plane, a distance B above the nucleus. It is deflected upwards in a hyperbolic path and its path becomes parallel to another ray out of the nucleus, distance A away from this ray. Show that A=B using conservation of...
