2) A uniform electric field exists in the region between two oppositely charged parallel plates 1.54 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 1.53E[-6] s. S. 1 Ax = v¡t +5at² v = v¡ + at v² = v? + 2aAx a) Find the magnitude of the electric field. Answer: 137 b) Find the speed of the proton at the moment it strikes the negatively charged plate. Answer: 2.01E[4]
