An electron that has velocity v = (3 x 105 m/s) and moves along positive x direction through the uniform magnetic field B = (0.8T) which is along the positive z direction.
a. Find the force on the electron (magnitude and direction).
(e =  1.6 x 1019 C, m=9.1 x1031 kg)
b. Calculate the radius of electron’s path in the magnetic field.

drwls,
(a) F = e V B
Use the right hand rule for direction
(b) Review the formula for the "Larmor radius" of a charge in a magnetic field.
