A particle of charge `q` and mass `m` moving with a velocity `v` along the x-axis enters the region `xgt0` with uniform magnetic field `B` along the `hatk` direction. The particle will penetrate in this region in the `x`-direction upto a distance `d` equal to

A

zero

B

`(mv)/(qB)`

C

`(2mv)/(qB)`

D

Infinity

Text Solution

Verified by Experts

The correct Answer is:
B
It is easy to understand the given problem, along with the following figure.
`d`=radius of path
` (mv)/(qB)`
