The force on an electric charge in an electric field is F = qE where F is the force, q is the electric charge, and E is the electric field. Determine the speed of a proton (charge = 1.6×10-19 C, mass = 1.67×10-27 kg) after it has been accelerated, from rest, a distance of 0.25 m though an electric field of 2.0×106 N/C.
