A bead of mass slides along a straight frictionless rigid wire rotating in a horizontal plane with a constant angular speed then the axes of rotation is perpendicular to the wire and
asses through one end of the wire. If r is the distance of the mass from the axis of rotation and
is its speed then the magnitude of coriolis force is -
Use, Coriolis force
Since the axes of rotation is perpendicular to the wire.
coriolis force
Since
Hence option 4 is correct.
