Official Correct Choice:
Option D: Volt per meter
1. Concept:

Electric field intensity can be measured either by the mechanical force it exerts on a charge or by the spatial gradient of its electric potential.

2. Formula:

$$ E = \frac{F}{q} = \frac{\Delta V}{\Delta r} $$

3. Solution:

  • Using the potential gradient definition (\( \Delta V / \Delta r \)), the unit naturally becomes Volts (for potential) divided by meters (for distance).


4. Why other options are incorrect:

Newton per Coulomb (N/C) is correct, but Newton per Volt or Ampere are dimensionally nonsensical for an electric field. Volt per Coulomb represents Energy per Charge squared.

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.
