a neutron an electron and an alpha particle moving with equal velocities , enter a uniform electrical magnetic field .trace the path of each particle.

1) The trajectory or the path of a particle inside a magnetic field is governed by the equation r = mv/qB.
 
where m is the mass of the particle,
v is the velocity,
q is the charge, and
B is the strength of the magnetic field
 
2) It is given that v is the same for all the three particles. The field is also uniform. So, the trajectory depends on the mass and the charge.
 
3) Now, the charge on the neutron is zero. So, there is no effect of the magnetic field and neutron continues to travel in the path it was originally moving.
 
4) The electron and the alpha particle move in a circle of different radii as their masses and charges are different.
