A neutron, an electron and an alpha particle moving with equal veloc

1.	A neutron, an electron and an alpha particle moving with equal velocities, enter a uniform magnetic field going into the plane of the paper as shown. Trace their paths in the field and justify your statement.
Answer» α particle will trace circular path in clockwise direction as it’s deviation will be in the direction (\(\vec v\) x \(\vec B\)) i .e, perpendicular to the velocity of particle. neutron will pass without any deviation as magnetic field does not exert neutral particle. Electron will trace circular path in anticlockwise direction as its deviation will be in the direction opposite to (\(\vec v\) x \(\vec B\)) with a smaller radius due to large charge/mass ratio as r = mv/qB
