At some instant the velocity components of an electron moving between two charged parallel plates are vx = 1.5 x 105 m/s and vy = 3.0 x 103 m/s. Suppose the electric field between the plates is given by E = (120 N/C)j. In unit-vector notation, what are?

(a) The electron's acceleration in that field and

(b) The electron's velocity when its x coordinates has changed by 2.0 cm?
