A proton is projected horizontally midway between two parallel plates that are separated by 0.51 cm. The uniform electric field has magnitude 6.1 x 105 N/C between the plates. If the plates are 5.5 cm long, find the minimum speed of the proton if it just misses the lower plate as it emerges from the field. The gravitational force on the proton can be neglected.
