Original Khojo Papers practice question — not from a past board paper.
To every action there is an equal and opposite reaction, and the two act on different bodies. A swimmer pushes the water backwards and is pushed forwards; a rocket pushes hot gases downwards and is pushed upwards.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
