Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Parallel to each other
1. Concept:

The electric field is explicitly defined based on the force experienced by a positive test charge. By standard physics convention, unless a negative sign is explicitly provided, we assume standard positive charge behavior.

2. Formula:

$$ \vec{F} = q \vec{E} $$

3. Solution:

  • Because \( q \) is a scalar multiplier, the resulting vector \( \vec{F} \) must lie along the exact same line as \( \vec{E} \). Thus, they are inherently parallel.


4. Why other options are incorrect:

They are anti-parallel (opposite) strictly for negative charges, but 'parallel' represents the baseline mathematical alignment of the vectors.

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.
