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\(\vec{B}=\frac{B_{0}}{2} \hat{i}+\frac{\sqrt{3} B_{0}}{2} \hat{j}\).
z-component of velocity is \(\frac{\sqrt{3} v_{0}}{2}\) after time t = ____.
- \(\frac{2 \pi m}{B_{0} q}\)
- \(\frac{\pi m}{B_{0} q}\)
- \(\frac{\pi m}{2 B_{0} q}\)
- \(\frac{2 \pi m}{4 B_{0} q}\)
Answer
(C) m 2 B_ 0 q
