Question: A uniform rope of length l lies on a table. If the coefficient of friction is $ \mu $ , then the maximum length $ l _{1} $ of the part of this rope which can overhang from the edge of the table without sliding down is [DPMT 2001]
Options:
A) $ \frac{l}{\mu } $
B) $ \frac{l}{\mu +l} $
C) $ \frac{\mu l}{1+\mu } $
D) $ \frac{\mu l}{\mu -1} $
Show Answer
Answer:
Correct Answer: C
Solution:
For given condition we can apply direct formula $ l _{1}=( \frac{\mu }{\mu +1} )\ l $
