Official Correct Choice:
Option A: 10 s\(^{-1}\)
Concept:

Frequency is defined as the total number of repetitive cycles (or pulses) generated per unit of time.

Formula:

$$ f = \frac{N}{t} $$

Solution:

  • Given: Number of pulses \( N = 500 \) and total time \( t = 50 \text{ s} \).


  • Substitute the values: \( f = \frac{500}{50} \).


  • \( f = 10 \text{ Hz} \).


  • Note that Hertz (Hz) is dimensionally equivalent to inverse seconds (\( \text{s}^{-1} \)). Thus, the answer is 10 \( \text{s}^{-1} \).


Why other options are incorrect:

Option B (0.1) is the Time Period (50/500), incorrectly inverted. Option C and D use raw numbers from the prompt without solving.

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.
