Motion of Charged Particle In Magnetic Field
question_answer
A particle of mass M and charge Q moving with velocity \[\overset{\to }{\mathop{v}}\,\]describes a circular path of radius R when subjected to a uniform transverse magnetic field of induction B. The work done by the field when the particle completes one full circle is [AIEEE 2003]
A) \[B\,Qv\,2\pi \,R\]
B) \[\left( \frac{M{{v}^{2}}}{R} \right)\,2\pi R\]
