A charge Q is uniformly distributed over a ring which is rotating with constant angular velocity `omega` about an axis passing through its centre and perpendicular to the plane. A wire which carries a current I is lying perpendicular  to the plane of the irng along its axis having one end at its centre. Find resultant magnetic force on the wire by the ring.
