Magnetic field due to currentHard
Question
A non relativistic α particle is moving along a circle of radius R with a constant angular velocity ω. Point A lies in the same plane at a distance 2R from the centre. Point A records magnetic field produced by α particle. If the minimum time interval between two successive times at which A records zero magnetic field is ′t′, find the angular speed ω, in terms of t.
Options
A.
B.
C.
D.None of these
⇒ θ = 
; ω =
