Question

Action and reaction forces are exerted on which bodies during an interaction?

This question was previously asked in
RRB NTPC 2025 Graduate CBT 2 Question Paper PDF (10-Jul-2026) (Shift 1)
The correct answer is

Two different bodies

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

These action and reaction forces always act on two different bodies, never on the same body, which is why they do not cancel each other out.

This law applies universally to any interacting bodies, whether at rest or in motion.

Hence, action and reaction forces are exerted on two different bodies during an interaction.
