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
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
$\frac{l}{L}$
$\frac{l}{{L + l}}$
$\frac{l}{{L - l}}$
$\frac{L}{{L + l}}$
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
$\mu = \frac{{{\rm{Lenght \,of \,chain\, hanging \,from \,the \,table}}}}{{{\rm{Lenght\, of\, chain \,lying \,on \,the \,table}}}}$ $ = \frac{l}{{L - l}}$
