A person is standing on the edge of a circular platform, which is moving with constant angular speed about an axis passing through its center and perpendicular to the plane of platform. If person is moving along radius towards axis of rotation then the angular velocity will:
Text Solution
Verified by ExpertsThe correct answer is:
C
Using conservation of angular momentum 
As person is coming towards axis, it's
distance from axis decreases. So moment of inertia also decreases.
From conservation of angular momentum:
as I decreases so, 
increases
