A hollow cylinder of diameter 20 cm is rotating about its own vertical axis. If the angular velocity of the cylinder is not less than 180 rpm, then a body remains attached on the inside wall of the cylinder and keeps rotating with the cylinder. What is the coefficient of rotating with the cylinder. what is the coefficient of friction between the body and the wall of the cylinder? Given, pi^(2) = 9.8.

1.	A hollow cylinder of diameter 20 cm is rotating about its own vertical axis. If the angular velocity of the cylinder is not less than 180 rpm, then a body remains attached on the inside wall of the cylinder and keeps rotating with the cylinder. What is the coefficient of rotating with the cylinder. what is the coefficient of friction between the body and the wall of the cylinder? Given, pi^(2) = 9.8.
