Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: None of the given options
Concept:

Identifying physical quantities requiring strictly directional data.

Solution:

  • Electric Flux is the dot product of Electric field (vector) and Area (vector), resulting in a pure scalar.


  • Work Done is the dot product of Force (vector) and Displacement (vector), also resulting in a scalar.


  • All forms of Energy (including Potential) are scalar quantities by definition.


  • Since none of the options require a spatial direction to be fully defined, "None of the given options" is correct.


Why other options are incorrect:

Students mistakenly associate "electric" or "work" with vectors because their component formulas contain vectors, but dot products always yield scalars.

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.
