A negatively charged particle enters a region between two parallel plates. Each plate (top and bottom) are Oppositely charged, hence there exists a uniform electric field between the plates (along with a gravitation field). Assume the particle travels straight through the region completely un-deflected and exits.

a) Determine and identify (below) the polarities of the plates and the resulting Electric Field direction inside the plated region needed so the particle travels through un-deflected:

b) If the particle has a mass of 28.5 mg and a charge of -7.6 μC, determine the Electric Field Strength E needed inside the plated region so the particle travels through un-deflected (Fnet = 0):
