Chapter 26, Problem 49(choose chapter or problem)
An electron is moving in a uniform 0.25-T magnetic field; its velocity components parallel and perpendicular to the field are both 3.1 Mm/s. (a) Whats the radius of the electrons spiral path? (b) How far does it move along the field direction in the time it takes to complete a full orbit about the field?
