Also find the displacement of a particle with charge twice that of an electron & mass 7344 times as large. Given: e/m = 1.76×1011 C/kg.

Subject: Applied Physics 2

Topic: Motion Of Charged Paqrticle In Electric And Magnetic Field

Difficulty: Medium


Magnetic field of 104Wb/m2 acts over a length of 3 cm in a given region. The distance from the centre of the field to the screen is 20 cm. If the accelerating voltage is 800V, calculate the electron beam deflection on the screen. Also find the displacement of a particle with charge twice that of an electron & mass 7344 times as large. Given: e/m = 1.76×1011 C/kg.

B=104Wb/m2l=3cm,d=20cm.VA=800V,Deflection=?,

Charge of an electron 1.61019

Mass of an electron 9.11031

DeflectionY=DlB(e/(2mVA))
