If we have a frictionless hollow tube and a ball which just fits into it. All the surfaces are frictionless.
Now if we put in the ball about at the center of tube and rotate the tube about one of its ends with a constant angular velocity ,then the ball swoops out of
the other end .
If we see from the ground frame then no radial force is acting as friction is absent,then how can we explain the motion of the ball.According to Newton's first law we need a force to change the state of motion.
How do we explain this
