The radius of curvature of the path of the charged particle in a uniform magnetic field is directly proportional to:
Correct answer: B. The momentum of the particle
- A. The energy of the particle
- B. The momentum of the particle
- C. The intensity of the field
- D. The charge on the particle
Explanation
Option B is correct.We know that the radius of the circular path in the magnetic field is given by: r= mv/qB . We know that mv is the momentum of the body. ∴r=P /qB ⇒r∝p :

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
