When a mass M hanging on a string, is lowered into a Black Hole slowly,

total braking energy is E.

Two objects of mass M would give energy two times E.

If Black Hole was two times bigger, braking energy would be same as before.

So, braking energy seems to be proportional to M only.

So, E=M*K

where K is a Black Hole constant.

What is the value of K?
