Questions
A uniform rope of length I lies on a table. If the coefficient of friction is '', then the maximum length l1 of the part of this rope which can overhang from the edge of the table without sliding down is:
detailed solution
Correct option is C
weight of the hanging part = frictional force on the tableif l1part is hanging its weight =MLl1g L-l1 is on the table and frictional force due to this = μMLL-l1g MLl1g=μMLL-l1g l1=μL-l1 l11+μ=μL l1=μL1+μTalk to our academic expert!
