PhysicsEasysingle choice

A neutron, a proton, an electron and an $α$ particle enter a region of uniform magnetic field with same velocities. The magnetic field is perpendicular and directed into the plane of the paper. The tracks of the particles are labeled in the figure. The electron follows the track

Options:

Answer:

Solution:

$r = \frac{m v}{B q}$

$r$ is least when $(\frac{m}{q})$ is least.

$(\frac{m}{q})$ is least for electron ,so electron will trace path with minimumm radius i.e. track $D$
