Tn electron in a television picture tube moves toward thefront of the tube with a speed of 7.6´106m/s along the xaxis (as shown in the figure). Surrounding the neck of the tube are coilsof wire that create a magnetic field of magnitude 0.024T, directed at an angle of 60° to the x axis and lying in the xy plane.(a)Calculate the magnetic force on the electron(take charge of an electron = 1.6´1019C)[2](b)Find a vector expression for the magnetic force on the electron [3](c)Explain what would happen tothe force if the electron moved in the direction of the field B[3]
