If an electron and a proton having same momenta enter perpendicular to a magnetic field, then

Options

  1. Acurved path of electron and proton will be same (ignoring the sense of revolution)
  2. Bthey will move undeflected
  3. Ccurved path of electron is more curved than that of the proton
  4. Dpath of proton is more curved

Correct answer

A. curved path of electron and proton will be same (ignoring the sense of revolution)

Step-by-step solution

r = mv / Bq is same for both
