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 rightfulness to the velocity of the electron beam. It seemed fairly conf development at first, shut up as we started working on the equation, the ideas involved were easily understandable. The b arely confusing part was defining the equation that we should use to adjudicate the results. Equipment: 1 Cathode Ray Tube (with deflection plates and a graph on the end) 1 powerfulness tote up seven-fold connectors          Our group hooked up the cathode Ray Tube to the power supply with the connectors, and shapeed it on. The first time we did this it didnt work, so we check out 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 light-green trunk 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 dust lined up in the center of the graph. We enforce 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 spot up with an equation that would produce the amount of total deflection. We worked on it for a while and our at tempts proved inadequate. Our TA gave us th! e 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) ...
