Expert Answer
A proton is kept in uniform electric field, it moves in the direction of the electric field from the higher potential to a lower potential. As it moves to a lower potential potential, the potential energy decreases hence, the kinetic energy increases.
As a proton kept in unifrom electric field, it gets accelerate in the direction of electric field.
Therefore, Force developed, F = qE = ma
where, E=electric field
q=charge on proton
m=mass of proton
a=acceleration of proton
