A particle of charge per unit mass α is released from origin with a velocity of \(\overrightarrow{\mathrm{v}}=\mathrm{v}_{0} \hat{\mathrm{i}}\)in uniform magnetic field \(\overrightarrow{\mathrm{B}}=\mathrm{B}_{0} \hat{\mathrm{k}}\). If the particle passes through a point P (0, y, 0) and then y is equal to
- \(\frac{-2 v_{0}}{B_{0} \alpha}\)
- \(\frac{\mathrm{v}_{0}}{\mathrm{~B}_{0} \alpha}\)
- \(\frac{2 \mathrm{v}_{0}}{\mathrm{~B}_{0} \alpha}\)
- \(\frac{-\mathrm{v}_{0}}{2 \mathrm{~B}_{0} \alpha}\)
Answer
(A) -2 v_ 0 B_ 0
