Magnetic field due to currentHard
Question
An electron and a proton are moving on straight parallel paths with same velocity. They enter a semiinfinite region of uniform magnetic field perpendicular to the velocity. Which of the follow ing statement(s) is / are true?
Options
A. They will never come out of the magnetic field region.
B.They will come out travelling along parallel paths.
C.They will come out at the same time.
D.They will come out at different times.
Solution
Both will travel in semicircular path
Since, m is different, hence time will be different
Since, m is different, hence time will be different
