Questions
A uniform rope of length L lies on a table. If the coefficient of friction is µ , the maximum fractional length of the hanging part of the rope from the edge of the table without sliding down is
detailed solution
Correct option is C
Suppose Length of the hanging part is 'x' . Therefore length of chain lying on the table is (L-x). If λ be the mass per unit length of the chain , thenλx.g = µ(λ (L-x)g)⇒ x/L = (µ / 1+µ )Talk to our academic expert!
