A uniform electric field exists in the region between two oppositely charged parallel plates 1.55 cm apart.

A uniform electric field exists in the region between two oppositely charged parallel plates 1.55 cm apart. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval 1.48×10−6 s.1. Find the magnitude of the electric field.2. Find the speed of the proton at the moment it strikes the negatively charged plate.
