An electron of mass m and charge e moves in a circular path in a magnetic field of flux density B. How long does it take to complete one orbit?
2meBπ
2Bmeπ
2πmBe
Be2πm
Correct answer is C
Motion of charged particles in Magnetic field
qvb = Mv2r
where q = e
Introducing Period (T) as time taken to complete one orbit = \frac{2πM}{qe}
