Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of1.9010⁷m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of5.4010¹⁵m/s². The phosphorescent screen is a horizontal distance of6.7cm away from the point where the electron is emitted.(a) How much time does the electron take to travel from the emission point to the screen? s (b) How far does the electron travel vertically before it hits the screen? cm
