A particle accelerates uniformly from rest to 60 rev/min in 10 seconds. Determine the magnitude of angular acceleration and angle rounded by the particle, and the number of revolutions for the time of motion.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
