A beam of alpha particles is fired horizontally with a speed of 3.6 105 m/s into a region where there is a vertical magnetic field of magnitude 0.168 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 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 doubled?
increase
decrease
stay the same
(c) Repeat part (a) for alpha particles with a speed of 7.2 105 m/s.

A physicist has developed a device that generates a beam of alpha particles (each of which is a helium nucleus, consisting of two protons, two neutrons, and no electrons). The device ejects a steady stream of 6440 alpha particles per second. You are testing different shielding materials for a test chamber that will house the alpha particle generator. You prepare a sheet of one potential material in an electrically neutral state, mount it on a perfectly insulating stand, and fire...

Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm
