An electron is accelerated from rest through a potential difference of 500 V. It then enters a uniform magnetic field of 0.54 T that points out of the page and is perpendicular to the direction of motion of the electron. Assume the electron is moving in the -x direction. Required:
a. What is the magnetic force (magnitude and direction) that acts on the electron?
b. What is the radius of the path the electron follows in the magnetic field?
c. Would the radius of the electron's path be smaller or larger if the charge of the electron were smaller?
