An electron and a proton are moving on straight parallel paths with same velocity. They enter a semi infinite region of uniform magnetic field perpendicular to the velocity.
Which of the following statement(s) is /are true?

A

they will never cpme cut of the magnetic field region

B

they will come out travelling along parallel paths

C

they will come out of the same time

D

they will come out at different times

Text Solution

Verified by Experts

The correct Answer is:
`B,D`
By diagram `B` is true
`T =(2pim)/(qB)`
`t prop m`
`m_(p) gt m_(e)`
`T_(p) gt T_(e)`
So, `D` is also true
