A vessel containing a liquid 'L' is balanced by a solid 'S' as shown below. Now two identical pieces of cork (which float on the liquid) are placed gently, one on the solid and one in the liquid. What will happen to the balance? The pan carrying the liquid will go down.

The pan carrying the solid 'S' will go down.

There will be no change in the balance

Depending on the density of 'S' either pan may go down
