Question: An electron is moving on a circular path of radius r with speed v in a transverse magnetic field B. e/m for it will be [MP PMT 2003]
Options:
A) $ \frac{v}{Br} $
B) $ \frac{B}{rv} $
C) Bvr
D) $ \frac{vr}{B} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ r=\frac{mv}{eB}\Rightarrow \frac{e}{m}=\frac{v}{rB} $
