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 1.5 X 10-6 seconds.
Find the magnitude of the Electric Field 148.7 in N/C.
The speed of the proton when it strikes the negatively charged plate in 21.33 km/s km/s.
