Two parallel plates are arranged horizontally and held at a potential difference of 10 kv, and they are separated by a distance of 7 cm. a proton enters the region halfway between the plates traveling parallel to the plates at a velocity of 3.2x107 m/s
(a)what is the electric field between these plates?
(b)what is the force this electric field places on the proton?
(c)what horizontal distance does the proton travel before striking one of the plates?
