Please explain the following 30th question with reason.
In a circular motion under magnetic field, the centripetal force is provided by the magnetic force.
(mv2)/r = qvB
r = (mv)/(Bq)
T = (2Πr)/v
Putting r = (mv)/(Bq)
T = (2Πm)/(Bq)
Time period is independent of the velocity of charged particle.
The correct option is D.
