4. Inside a particular cathode ray tube, there is a uniform electric field with a magnitude 431 N/C pointing in the positive x-direction. An electron, initially at rest, moves a distance of 2.70 cm in this field. (a) How much work (in J) does the electric field do on the electron? J (b) What is the change in potential energy (in J) of the entire system (cathode ray tube plus electron)? J (c) What is the velocity (in m/s) of the electron after it moves the 2.70 cm distance? magnitude m/s direction Need Help? ---Select--- ◊ Read It
