A uniform electric field exists in the region between two oppositely charged parallel plates 1.67cm 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 1.53×10?6s .
part A: Find the magnitude of the electric field. Use 1.60×10?19C for the magnitude of the charge on an electron and 1.67×10?27kg for the mass of a proton.
Part B: Find the speed of the proton at the moment it strikes the negatively charged plate.
