A particle of charge $q$ and mass $m$ is moving with a velocity $- v \hat{i} (v \neq 0)$ towards a large screen placed in the $Y - Z$ plane at distance d. If there is magnetic field $\vec{B} = B_{0} \hat{k},$ the minimum value of $v$ for which the particle will not hit the screen is :

Options:

Answer:

Solution:

The radius of circular path in given magnetic field is

$r = d = \frac{m v}{q B_{0}}$

so $v = \frac{q B_{0} d}{m}$
