Answer:
Dear student,
 
Let m = mass of chain,
l = length of chain, l'= is the maximum length of chain that can be hung over one edge of the table.
mass per unit length = m/l
At equilibrium,
 
mue X (1-l')(m/l) X g = l' (m/l) X g,
Hence solving, we get
l' = 0.2 l
Friction = l'/l X 100 = 20%
 
Hope this helps.
