Question

A beam of alpha particles is fired horizontally with a speed of 4.5 x 105 m/s into a region where there is a vertical magnetic field
of magnitude 0.337 T. An alpha particle is the nucleus of a helium atom and as such, consists of two protons, two neutrons, and
has a mass of 6.64 x 10-27 kg.
(a) Determine the length of time it will take an alpha particle to move halfway around a complete circle.
S
(b) Does the time found in part (a) increase, decrease, or stay the same, if the speed of the alpha particle is tripled?
increase
decrease
Ostay the same
(c) Repeat part (a) for alpha particles with a speed of 1.4 x 106 m/s.
S
