A proton moving to the right at 6.2 × 10^5 ms^-1 enters a regionwhere there is an electric field of 62 kNC^-1 directed to the left.Describe qualitatively the motion of the proton in this filed. Whatis the time taken by the proton to come back to the point where itentered the field? (Use the standard values of the mass and chargeof a proton) Be as descriptive as possible, please!
