A neutron enters a magnetic field of strength B(Tesla) perpendicular to the magnetic lines of force, with speed v. The force on the neutron is zero.

Helping Concept

Because a neutron is a neutral particle and when it is entered into a magnetic field it will not deflect in the magnetic field. Only charged particles (electron or proton experience magnetic force).

Therefore, the correct option is (A).
