An electron has an initial velocity v_0 vector = (7.5 times 10^4 m/s)i cap. It enters a region where E vector = (2.0 I vector +8.0 j vector) times 10^4 N/C. Determine the vector acceleration of the electron as a function of time. m/s^2 i vector m/s^2 j vector At what angle theta is it moving (relative to its initial direction) at torque = 1.4 ns? degree (counterclockwise from its initial direction is positive)
