Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: The gravitational force between the two bodies
Concept:

Weight inherently IS the gravitational force.

Solution:

  • The gravitational force acting downwards on an object is perfectly synonymous with its weight.


Why other options are incorrect:

Inertia and binding energy strictly require scalar mass.

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.
