Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . 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 of 3.20Γ10-6 s. 1-find the magnitude of the electric field. use 1.60Γ10-19c for the magnitude of the charge on an electron and 1.67Γ10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate
