Question

N electron and a proton of equal linear momentum enter in the direction perpendicular to uniform magnetic field. If the radii of their circular paths be

Answer 1

$\huge\mathcal{answer}$

________________________________

As radius of charged particle in magnetic field is

r=mvBq

r=mvBq

the ratio of their radii is 1.

because q, m,v and B are equal

Answer : 1:1
