5 pts A proton is moving in the combined electric and magnetic fields shown in the figure. The magnitude of the proton's acceleration is I X 10^ m/s2 (your answer should have only one non-zero number before the decimal place, for example 250 x 109 should be entered as 2.5 x 10). The direction of the proton's acceleration is (your answer here should be "up","down", "left", "right", "into the page", or "out of the page"), B = 2.5 T X х х X х X X X Х х X x х 500 m/s Х x х x х X X X x х х X х E = 1000 V/m
