An electron (mass 9 x 10731kg) is traveling at a speed of 0.800 cin an electron accelerator. An electric force of 1.9 x 10-13 N is applied in the direction of motion while the electron travels a distance of 0.4 m. Part 1 Your answer is incorrect. (a) You need to find the new speed of the electron. Which of the following steps must be included in your solution to this problem? Calculate the net work done on the electron. Calculate the final particle energy y, mc of the electron. O Use the final energy of the electron to find its final speed. O Determine how much time it takes to move this distance. Calculate the initial particle energy y, mc of the electron. Use the formula - mu to find the kinetic energy of the electron. Save for Later Last saved 1 second ago.
