1. B a) Figure above shows an electron moving in uniform magnetic field, B= 1.2 T (B is moving out of the page) with velocity, v = 3.2 x 10 m s that are perpendicular with B. i. Draw the path and direction of the electron when it is moving in the magnetic field. Label the force, F exerted on the electron. Explain why the electron is moving in the path you drawn. ii. Determine the radius of the electron path. 111. Calculate the orbital period of the electron. b) If an electric field, E is added to the magnetic field in certain direction, the electron now is moving in a straight line in +x direction. Draw a diagram to show the direction of electric field, E and determine the magnitude of E
