The velocity associated with a proton moving in a potential difference of 1000 V is4.37 × 105ms–1

A proton is moving through a magnetic field of magnitude 4.40 × 10–3 T. The proton experiences only a magnetic force of 3.3 × 10–15 N. At a certain instant, it has a speed of 4.25 × 105 m s–1. Determine the angle (less than 90°) between the proton's velocity and the magnetic field.
