An electron in a TV picture tube moves toward the front of the tube with a speed of V = 5.10 m/s. Surrounding the neck of the tube are coils of wire that create a magnetic field of magnitude B=0.1 T, directed at an angle of 0= 30°. Calculate the magnetic force F on the electron. (Charge of the electron: q=1.6x10-19 C)
