Distinguish between stable and unstable equilibrium, giving one example of each.
Original Khojo Papers practice question — not from a past board paper.
Answer
A body is in stable equilibrium if, when slightly displaced, its centre of gravity rises and it returns to its original position — a cone resting on its base, for example. It is in unstable equilibrium if, when slightly displaced, its centre of gravity falls and it moves further away — a cone balanced on its apex.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
In neutral equilibrium the centre of gravity stays at the same height, as with a ball on a level table.
