a) A proton enters a uniform magnetic field B in a perpendicular direction. The proton is moving out page with a speed of 1.00 x 107 m/s when it enters the magnetic field After entering the magnetic field the proton experiences acceleration of 2.00 x 1013 m/s2 in + x direction. Determine the magnitude and direction of the magnetic field B?
b) Find the direction of the magnetic field acting on an electron moving through two situations shown in the figure below. (Note: The directions of velocity and force are shown in each case.)
