A uniform electric field exists in the region between two oppositely charged plane parallel plates. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate, 1.40 cm distant from the first, in a time interval of 2.30x10-6 s. Part A Find the magnitude of the electric field. Express your answer with the appropriate units. HẢ ?
