Question 2

What happens when you try to hold the ring in equilibrium with the two spring balances not lying along one line?

A It can be done only if the ring is heavy B It cannot be done C It can be done only by increasing both forces D It is easily done

The right answer is the one marked above.

It cannot be done. In every case where the ring is in equilibrium the two forces must be collinear.

No change to the magnitudes can fix this. What is missing is not size but the line.
