1.	A hollow vertical cylinder of radius R and height h has smooth internal suface. A small particle is placed in contact with the inner side of the upper rim at a point P. It is given a horizontal speed v_(0) tangential to rim.It leaves the lower rim point Q vertically below P. The number of revolutions made by the particle will:
Answer» `h/(2piR)` `(v_(0))/(sqrt(2gh))` `(2piR)/(h)` `(v_(0))/(2piR)(sqrt((2H)/(G)))` ANSWER :D
