An electron (e = 1.6 x 10-19 c, me = 9.11 x 10-31 kg) begins at rest with potential energy 1.6 x 10-16 j and is accelerated to its final speed (with no potential energy) before entering a region of constant electric field of 5000 n/c between two parallel plates. the plates are separated by a distance d = 2 cm, and each has a length l = 4 cm. the electron enters the region moving parallel to the plates, exactly half-way between the two. does the electron collide with either of the plates? if yes, where (at what horizontal distance) does it strike a plate, and how fast is it moving before it does so? if no, by what (vertical) distance is it deflected and how fast is it moving as it leaves the region between the plates
