Q164 / 225 · JEE Main 2002 · Physics

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

Correct answer
A
curved path of electron and proton will be same (ignoring the sense of revolution)
B
they will move undeflected
C
curved path of electron is more curved than that of the proton
D
path of proton is more curved

Solution

r = mv / Bq is same for both

Hence, the correct answer is option: 'A'.
