Physics Lab Report

In this lab our backpack was to find how the excursus of the electron beam varies when passing by means of an electric field properly to the velocity of the electron beam. It seemed slightly conf victimisation at offset printing, lighten as we started working on the equating, the ideas involved were easily understandable. The b arely confusing part was delineate the equation that we should use to give chase the results. Equipment: 1 Cathode Ray supply (with deflection plates and a map on the end) 1 office tote up fivefold connectors          Our group hooked up the cathode Ray Tube to the magnate supply with the connectors, and daily rounded it on. The first time we did this it didnt work, so we check into with the TA and found that we were supply too many volts to the CRT. We were using 500V or else of 250V. We fixed this trouble and a leafy ve astonishable remains appeared on the screen at the end of the CRT. Because gravity and magnetic handle in the fashion were acting on the CRT, we had to turn it about to find a plane in which the green constellate lined up in the center of the graph. We utilise this as our point of origin. We so proceeded to measure the withdrawnness the dot traveled resulting from several contrastive potential drops applied to the deflection plates. The deflection plates used the voltage to arrive at the electrons change their path.

With more voltage the electrons were deflected a farther distance from origin.         I was unable to buzz off up with an equation that would aver the amount of total deflection. We worked on it for a while and our attempts be 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) ...
