Dear student,
The mass per unit length of the string would be given by:

Hence, the mass of the chain that is kept on the table would be given by:

Thus, the frictional force acting on the chain kept on the surface would be given by:

The weight of the chain that is hanging would be given by:

Hence, if the masses have to be balanced, then
