Answer parts a, c, and d.

Problem 4: A proton moves in a circular path of the same radius as a cosmic ray electron moving at 6.5 x 10° m/s perpendicular to the Earth's
magnetic field at an altitude where the field strength is 1.0 x 10-5 T.
Part (a) What will the speed of the proton be in m/s?
= 3.5 * 10(6)
= 3500000 X
Part (b) What would the radius of the path be in meters if the proton had the same speed as the electron?
"2, = 6.78 * 10(3)
rey = 6780 v Correct!
Part (c) What would the radius be in meters if the proton had the same kinetic energy as the electron?
Part (d) What would the radius be in meters if the proton had the same momentum as the electron?
