A beam of protons exits from a particle accelerator due east at a speed of 3.0 x 105 m/s. The protons then enter a uniform magnetic field of magnitude 0.50 T that is oriented at above 37o the horizontal relative to the beam direction.
(a) What is the initial acceleration of a proton as it enters the field?
(b) What if the magnetic field were angled at below the horizontal instead?
(c) If the beam were made of electrons traveling at the same speed rather than protons and the field were angled upward at 37o, would there be any difference in the force on the electrons compared to the protons? Explain.
(d) In part (c), what would be the ratio of the acceleration of an electron to that of a proton?
