In this https://youtu.be/YCrFwQtW5o0 sir took a disk and demonstrated that the particles kept on it fly away due to centrifugal force.
Now, suppose I take a ring in free space and a placed particle in its interior (Not on circumference).
If we observe it from a frame of reference of the ring, since ring is rotating the particle must experience a centrifugal force and hence it will fly off.
But from space frame, it doesn't.
Why does this happen?
I am also attaching a picture of my demonstration.
In the picture there are two scenarios first is the same as shown in the video .
In the second picture will the particle experience a centrifugal force or is it n it is necessary that the particles must somehow interact with the rotating frame to experience a pseudo force.
