A charged particle is moving in a magnetic field of strength B perpendicular to the direction of the field. If q and m denote the charge and mass of the particle respectively, then the frequency of rotation of the particle is
- \(f=\frac{q B}{2 \pi m}\)
- \(f=\frac{q E}{2 \pi m^{2}}\)
- \(f=\frac{2 \pi^{2} m}{q^{B}}\)
- \(f=\frac{2 \pi m}{q^{B}}\)
Answer
(A) f= q B 2 m
