Physics · JEE | Moving Charges and Magnetism
हिन्दीThe angular frequency \( \omega \) of a charged particle \( q \) of mass \( m \) moving in a uniform magnetic field \( B \) is:
View Answer & Solution
Correct answer · Option B
\( \omega = \frac{qB}{m} \)
Explanation
Equating magnetic force to centripetal force \( \frac{mv^2}{r} = qvB \) and substituting \( v = \omega r \) yields \( \omega = \frac{qB}{m} \).
