To which of the following quantities, the radius of the circular path of a charged particle moving at right angles to a uniform magnetic field is directly proportional?
- A energy of the particle
- B magnetic field
- C charge of the particle
- D momentum of the particle
Answer & Solution
Correct Answer
(D) momentum of the particle
Step-by-step Solution
Detailed explanation
If velocity of particle, \(\mathrm{v}\) is perpendicular to magnetic field, \(\mathbf{B}\) i.e. \(\theta=90^{\circ},\) then particle will experience maximum magnetic force, i.e. \(F_{\max }=q v B .\) This force acts in a direction perpendicular to the motion of charged particle.…
