An electron (mass 9 x 10⁻³¹ kg) is traveling at a speed of 0.884c in an electron accelerator. An electric force of 2.1 x 10⁻¹³ N is applied in the direction of motion while the electron travels a distance of 0.6 m
You need to find the new speed of the electron. Which of the following steps must be included in your solution to this problem?
a. Use the final energy of the electron to find its final speed.
b. Use the formula (1/2)m|v|² to find the kinetic energy of the electron.
c. Calculate the initial particle energy γᵢmc² of the electron
d. Calculate the final particle energy γmc² of the electron
e. Determine how much time it takes to move this distance.
f. Calculate the net work done on the electron.
