Tension in the chain from a distance

  • #1

Homework Statement


A chain of mass ##M## and length ##L## held vertically by fixing its upper end to a rigid support. The tension in the chain at a distance ##y## from the rigid support is

Homework Equations


##F=ma## (Newton's 2nd law)

The Attempt at a Solution


Since net acceleration, ##a=0##,
Therefore, ##F=0##
Hence, ##T=Mg##,
Then onward I don't seem to get my head around.
The answer given is :
##\frac{Mg(L-y)}{L}##
