Proton in an Electric Field Potential difference `(DeltaV)` between two points `A and B` separated by a distance `x`, in a uniform electric field `E` is given by `DeltaV =-Ex`, where `x` is measured parallel to the field lines. If a charge `q_0` moves from A to B, the change in potential energy `(DeltaU)` is given as `DeltaU=q_0 DeltaV`. A proton is released from rest in uniform electric field of magnitude `8.0 xx 10^4 Vm^(-1)` directed along the positive X-axis. The proton undergoes a displacement of 0.50 m in the direction of E.Mass of a proton `= 1.66 xx 10^(-27)
