Physics Lab Report

In this lab our throng was to find how the excursion of the negatron beam varies when passing through an electric field effective to the velocity of the electron beam. It seemed fairly conf utilize at first, quiet down as we started working on the compare, the ideas involved were easily understandable. The b arely confusing part was defining the equation that we should use to distinguish the results. Equipment: 1 Cathode Ray Tube (with deflection plates and a chart on the end) 1 might tote up quadruplicate connectors          Our group hooked up the cathode Ray Tube to the power supply with the connectors, and unfreezeed it on. The first time we did this it didnt work, so we check up on with the TA and found that we were supplying too many volts to the CRT. We were using 500V or else of 250V. We fixed this problem and a discolour besprinkle appeared on the screen at the end of the CRT. Because gravity and magnetic handle in the room wer e acting on the CRT, we had to turn it about to find a plane in which the green dispel lined up in the center of the graph. We utilise this as our point of origin. We then proceeded to measure the distance the dot traveled resulting from several different potential differences applied to the deflection plates. The deflection plates used the voltage to make the electrons change their path.

With more voltage the electrons were deflected a farther distance from origin.         I was unable to shape up up with an equation that would produce the amount of total deflection. We worked on it for a while and our attempts proved inadequate. ! Our TA gave us the equation: tot Deflection = E L (D + L/2) 2 Vacc         These are your readings from the chart on the end of the CRT: Y          case (mm) ...
