Questions
A heavy uniform chain lies on horizontal table top. If the coefficient of friction between the chain and the table surface is 0.5, the maximum percentage of the length of the chain that can hang over one edge of the table is
detailed solution
Correct option is B
weight of the hanging part = frictional force on the table if lnis hanging mgln=μmgl-ln 1=μn-1 μ=0.5 n=3 so 13 is hangingTalk to our academic expert!
