A particle of charge $q$ and mass $m$ moving with a velocity $v$ along the $x$-axis enters the region $x 0$ with uniform magnetic field $B$ along the $\widehat{k}$ direction. The particle will penetrate in this region in the $x$-direction upto a distance $d$ equal to

Question

A particle of charge $q$ and mass $m$ moving with a velocity $v$ along the $x$-axis enters the region $x > 0$ with uniform magnetic field $B$ along the $\widehat{k}$ direction. The particle will penetrate in this region in the $x$-direction upto a distance $d$ equal to

(b) It is easy to understand the given problem, along with the following figure
$d =$ radius of path
$= \frac{mv}{qB}$
