Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Temperature of charges
1. Concept:

Coulomb's Law provides an exact accounting of the variables required to calculate static electrical force.

2. Formula:

$$ F = \frac{1}{4 \pi \epsilon} \frac{q_1 q_2}{r^2} $$

3. Solution:

  • The equation explicitly requires: Charge magnitudes (\( q_1, q_2 \)), spatial distance (\( r \)), and the medium's permittivity (\( \epsilon \)).


  • Temperature does not appear in the foundational laws of macro-electrostatics and has no bearing on the isolated electrostatic force magnitude between two points.


4. Why other options are incorrect:

Distance, magnitude, and the intervening medium are the literal three pillars that define Coulomb's Law. Changing any of them will drastically alter the force.

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.
