Question

Which of the following law applies if body 'A' exerts force on body 'B' and simultaneously body 'B' exerts the same force on body 'A'?

• A. Law of Inertia
• B. Law of Momentum
• C. Law of Reaction
• D. Law of Gravity

Answer 1

The Correct Option is C

This query pertains to a fundamental principle in physics, particularly within Newtonian mechanics. The scenario where object 'A' applies a force to object 'B', and object 'B' reciprocally applies an equal and opposing force to object 'A', exemplifies Newton's Third Law of Motion. This principle is also referred to as the Law of Reaction. Its correct interpretation is detailed below:

1. Newton's Third Law posits that for every force (action), there exists an equal and opposing force (reaction).
2. In this context, the force exerted by 'A' on 'B' constitutes the action, and the force exerted by 'B' on 'A' represents the reaction.
3. These paired forces are identical in magnitude and opposite in direction.

Consequently, the accurate identification is the Law of Reaction.
