Problem:
A proton is shot into an electric field of magnitude 2.5 × 104 𝑁𝐶 −1 . If the velocity of the proton
as it enters the field is 106 𝑚𝑠 −1 and is perpendicular to the field, what is magnitude and
direction of the velocity after 3 seconds of motion in the field? Comment on your results
considering the speed of light is 3 × 108 𝑚𝑠 −1 .
