At one instant an electron is moving in the xy plane, the components of its velocity being U = 5 x 10°m/s and v, = 3 x 10°m/s. A magnetic field of 0.8T is in the positive x- direction. At that instant the magnitude of the magnetic force on the electron is: 3.8 x 10-14 N 6.4 x 10-14 N 1.0 x 10-13 2.6 x 10-14 N
