A proton enters the uniform electric field produced by the two charged square plates shown below. The plates carry charges +Q and -Q, where the magnitude Q=1.4 µC. The speed of the proton when it enters the region between the plates is 3.5 × 107 m/s. 12.0 cm- Figure Description Hint a. What is the magnitude of electric field in the region? Assume that the plates are close enough together to be treated as "infinite" planes for electric field between them. d E N/C. b. What distance d has the proton been deflected downward when it leaves the region between the two plates? Assume that the electrostatic force is the only force on the charge. d cm.
