A uniform chain of length \(L\) is lying on the horizontal table. If the coefficient of friction between the chain and the table top is \(\mu\), what is the maximum length of the chain that can hang over the edge of the table without disturbing the rest of the chain on the table?
- A \(\frac{L}{(1+\mu)}\)
- B \(\frac{\mu L}{(1+\mu)}\)
- C \(\frac{L}{(1-\mu)}\)
- D \(\frac{\mu L}{(1-\mu)}\)
Answer & Solution
Correct Answer
(B) \(\frac{\mu L}{(1+\mu)}\)
Step-by-step Solution
Detailed explanation
Let \(l^{\prime}\) part of the chain is hanging over the edge of table without sliding. \(\therefore \quad \mu=\frac{\text { Length hanging over the edge }}{\text { Length lying on the table }}\) (As the chain have uniform linear density)…
