Question: Protons from a Van de Graaff accelerator are released from rest at a potential of 5 MV and travel through a vacuum to a region

Protons from a Van de Graaff accelerator are released from rest at a potential of 5 MV and travel through a vacuum to a region at zero potential.

(a) Find the final speed of the 5-MeV protons.

(b) Find the accelerating electric field if the same potential change occurred uniformly over a distance of 2.0 m.
