A proton moves with a velocity of V : (2i 5i + I?) m/s in a region in which the magnetic field is E = (i + 23 Q) T. What is the magnitude of the magnetic force this particle experiences? l 1 1.69719 ,4 Check your evaluation of the cross product as this is a likely source of error in your calculation. N Calculate velocity of the object at the bottom, if h = 13 meters. Friction coefficient = 0.1 and mass = 50 kg 2 m/s h 3 meters
