Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Work done
Concept:

Integrating Force over Displacement yields the total Work Done.

Formula:

$$ W = \int_{x_i}^{x_f} F dx $$

Solution:

  • The product of the units on the axes is Newton \( \times \) meters (N.m), which is Joules.


  • Joules are the unit of Work. Hence, the geometric area represents Work Done.


Why other options are incorrect:

Area is a geometric measure, not a physical quantity. Power is Force \( \times \) Velocity.

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.
