A Neutron is moving with a velocity of V in a non-uniform magnetic field as shown in the figure. Velocity v̅ of neutron would be:
Same at A, B, and C
Neutrons are neutral particles and are not affected by magnetic fields as they do not experience a Lorentz force.
- Unlike charged particles, which experience a force in a non-uniform magnetic field, a neutron moves without being deflected or accelerated.
- This means that its velocity remains constant at all points A, B, and C.
Thus, the correct answer is (b) Same at A, B, and C.
