Assume that a proton has a mass of 3.34 × 10-27Kg and a charge of +e. It travels in a circular path with a radius 6.96mm in a magnetic field with magnitude 2.50T.
a) Find the time required for it to make half a revolution.
b) Find the speed of the proton.
c) Through what potential difference would the proton have to be accelerated to acquire this speed?
