An electron is moving east in a uniform electric field of 1.55 N/C directed to the west. At point A, the velocity of the electron is 4.49×10⁵ m/s pointed toward the east. What is the speed of the electron when it reaches point B, which is a distance of 0.370 m east of point A? the answer for this question is 6.35*10⁵m/s
Part b )A proton is moving in the uniform electric field of part A. At point A, the velocity of the proton is 1.88×10⁴ m/s , again pointed towards the east. What is the speed of the proton at point B?
