1 A particle is gently placed on a frictionless rotating turntable at a distance r from the centre.Describe particle motion from both ground and table frame.
2 A particle is at a distance r from the centre of a frictionless stationary turntable.The turntable then starts rotating. Describe particle motion from both ground and table frame.
The Attempt at a Solution
If sufficient friction is present then the particle will also rotate with same angular velocity.But I am not sure what if the surface is frictionless.Are the two cases same or different?Please help...
