Q. 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 conflicting plate in a time interval 1.48×10-6s.
Find out the magnitude of the electric field.
Make use of 1.60×10-19 C for the magnitude of the charge on an electron and 1.67×10-27 kg for the mass of the proton.
