Mass of alpha particles is 6.64 x 10-27 Kg and their charge is 3.20 x 10-19 Can alpha particle emitted by a move into a region of uniform field given by B (2.0T)i+(3.20)j At a given moment, the alpha particle has a velocity v (12.00 x 104 m/s)i. Find the magnitude (a) and ii) direction of its acceleration vector at this particular
