Question

At some instant the velocity components of an electron moving between two charged parallel plates are vx = 1.3 105 m/s and vy = 3.6 103 m/s. Suppose that the electric field between the plates is given by E = (120 N/C) j.
(a) What is the electron's acceleration in the field?
m/s2 j
(b) What is the electron's velocity when its x coordinate has changed by 4.8 cm?
m/s i + m/s j
