Looking for help on this thank you!

V Part A A uniform electric field exists in the region between two oppositely charged parallel plates 1.57 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 1.56x10-6 s Find the magnitude of the electric field . Use 1.60x10-19 C for the magnitude of the charge on an electron and 1.67x10-27 kg for the mass of a proton. View Available Hint(s) IVO AEd 5 0 0 82 ? N/C Submit Request Answer Part B Find the speed of the proton at the moment it strikes the negatively charged plate. View Available Hint(s) IVO AEQ m/s Submit
