Chapter 28, Problem 004
An alpha particle travels at a velocity of magnitude 760 m/sthrough a uniform magnetic field of magnitude 0.042 T. (An alphaparticle has a charge of charge of +3.2 × 10-19 C and amass 6.6 × 10-27 kg) The angle between the particle'sdirection of motion and the magnetic field is 62°. What is themagnitude of (a) the force acting on the particledue to the field, and (b) the acceleration of theparticle due to this force? (c)Does the speed ofthe particle increase, decrease, or remain the same?
