An electron (q = -1.6E-19 C, m = 9.1E-31 kg) has an initialvelocity (t=0) of v = 1.6E5 m/s j + 2.4E5 m/s k and is moving in a magneticfield B = 0.5 T k.
a. What is the force on the electron from the magnetic fieldat t = 0?
b. What is the radius of motion of the electron?
c. After 5 seconds, how far will the electron progress downthe z-axis?
