Give the derivation of charge to mass ratio please

Asked by Braham | 10th Apr, 2013, 11:55: AM

Expert Answer:

The charge to mass ratio of the electron is given by

e/m = E / B X B x r

Where e charge of an electron,m = mass of electron ,E = strength of e;ectric field

B = strength of magnetic field and r = radius of the circular path describe by electron in magnetic field.
