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 1.60 cm distant from the first in a time interval of 1.5 * 10^-6 seconds. Find the magnitude of the Electric Field in N/C and the speed of the proton when it strikes the negatively charged plate in km/s.
