(a.) The acceleration voltage is 5.0kV . Calculate the speed of the of the electrons as they emerge from the anode. (b.) The apparatus is situated in a uniform magnetic field acting into the plane of the diagram. Explain why the path followed by the beam is circular. Calculate the radius of the circular path for a flux density of 2.0 x 10-3T. (c.) Suggest a possible process by which the gas in the tube might make the path of the beam visible.

Question

The diagram shows a type of cathode ray tube containing a small quantity of gas. Electrons from the hot cathode emerge from a small hole in a conical shaped anode and the path subsequently followed is made visible by the gas in the tube.
