Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Action and reaction can cancel each other
Concept:

Newton's Third Law governs action and reaction force pairs.

Solution:

  • Forces can mathematically cancel each other out ONLY if they are applied to the exact same object.


  • Newton's Third Law pairs (Action/Reaction) ALWAYS strictly apply to two different interacting bodies (A pushes B, B pushes A).


  • Because they act on different bodies, they dictate the respective motion of those different bodies independently. They can never cancel each other. Therefore, Option D is a false statement.


Why other options are incorrect:

Options A, B, and C are entirely true properties of Newton's Third Law.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
