Laws Of Motion Question 360
Question: A uniform chain of length L changes partly from a table which is kept in equilibrium by friction. The maximum length that can withstand without slipping is l, then coefficient of friction between the table and the chain is [EAMCET (Engg.) 1995]
Options:
A)$ \frac{l}{L} $
B) $ \frac{l}{L+l} $
C) $ \frac{l}{L-l} $
D) $ \frac{L}{L+l} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \mu =\frac{\text{Length of chain hanging from the table}}{\text{Length of chain lying on the table}} $
$ =\frac{l}{L-l} $
