A proton is projected horizontally midway between two parallel plates that are separated by 0.50 cm. The electrical field due to the plates has magnitude 610,000 N/C between the plates away from the edges. The plates are 5.60 cm long. (e = 1.60 × 10-19 C, mp = 1.67× 10-27 kg). a) Calculate the electric force acting on the particle and its acceleration. Indicate the direction of the force and of the acceleration. b) Find the minimum speed of the proton if it just misses the lower plate as it emerges from the field.
