## 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}##
