106as there is no slipping and the string passes through the topmost point .. therefore length of the string passing through the man = 2Xcm as there is no slipping .. hence length of string passing thru man = 2l
A string of negligible thickness is wound around a cylinder on a rough surface, several times.A man standing at a distance l from the cylinder holds one end of the string . THere is no slipping,find the length of string passing thru the man's hand when the cylinder reaches his hands
