[1.] {10 pts) A proton travels with a speed ofv = 5.02X 10"J mi's in the xy plane, in a direction that makes an angle of 60.0 with a E-eld. The Eeld has magnitude 3 = 0.180 T in the positive xdirection. What are the magnitudes of (a) the magnetic force on the proton and (b) the proton's acceleration? (c) Give the 2 possible directions for the magneticforce on the proton. Let the page be the xy plane, with +2 being out of the page, as shown below
