6. In New England, the horizontal component of the Earth's magnetic field has a magnitude of 1.60 x 10-5 T. An electron is shot vertically straight up from the ground with a speed of 2.10 x106 m/s. Ignore the gravitational force acting on the electron.

a. What is the magnitude of the acceleration caused by the magnetic force?

b. In what direction is the force initially?

c. Describe the subsequent path of the electron.
