Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: 20 m/s²
Concept:

Newton's Second Law directly relates force, mass, and acceleration.

Formula:

$$ F = ma \implies a = \frac{F}{m} $$

Solution:

  • Force \( F = 10 \text{ N} \).


  • Mass \( m = 0.5 \text{ kg} \).


  • Substitute values: $$ a = \frac{10}{0.5} $$


  • $$ a = 20 \text{ m/s}^2 $$


  • Note: The options provided in the source use 'N' as the unit, which is a typographical error in the original paper (it should be \( \text{m/s}^2 \)). We select 20 based on the numerical value.


Why other options are incorrect:

Multiplying 10 by 0.5 yields 5. Mathematical errors in division yield 40 or 10.

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.
