A particle having a charge q and mass m is projected from origin with velocity \(\vec{v}=v_{0} \hat{i}\) in a uniform magnetic field\(\vec{B}=\frac{B_{0}}{2} \hat{i}+\frac{\sqrt{3} B_{0}}{2} \hat{j}\).
Pitch of the helical path described by the particle is
- \(\frac{2 \pi m v_{0}}{q B}\)
- \(\frac{\pi m v_{0}}{q B_{0}}\)
- \(\frac{5 \pi m v_{0}}{q B}\)
- \(\frac{6 \pi m v_{0}}{q B}\)
Answer
(B) m v_ 0 q B_ 0
