Physics Lab Report

In this lab our throng was to find how the difference of the negatron beam varies when passing through an electric field business to the velocity of the electron beam. It seemed fairly conf using at first, solace as we started working on the comparability, the ideas involved were easily understandable. The b arely confusing part was defining the equation that we should use to enounce the results. Equipment: 1 Cathode Ray Tube (with deflection plates and a graph on the end) 1 source tote up fourfold connectors          Our group hooked up the cathode Ray Tube to the power supply with the connectors, and crimped it on. The first time we did this it didnt work, so we study 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 commonality system appeared on the screen at the end of the CRT. Because gravity and magnetic handle in the room were acting on the CRT, we had to turn it about to find a plane in which the green tip lined up in the center of the graph. We go for this as our point of origin. We then proceeded to measure the distance the dot traveled resulting from several different potential drops 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 condescend up with an equation that would produce the amount of total deflection. We worked on it for a while and our attempts prov ed 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) ...
