Question

A cathode ray tube is shown below. Calculate the force on a 1C negative target charge as it passes in front of the magnet. Assume the electrons are moving horizontally in front of the magnet. Ignore the south pole of the magnet and ignore that the electrons may slow down slightly after passing through the positive plate.
