Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Formula
$n = \frac{p v}{2l}$ where $p$ is the number of segments.
Step 2: Calculation
$n = \frac{5 \times 20}{2 \times 10} = \frac{100}{20} = 5 \text{ Hz}$.
Final Answer: (A)
$n = \frac{p v}{2l}$ where $p$ is the number of segments.
Step 2: Calculation
$n = \frac{5 \times 20}{2 \times 10} = \frac{100}{20} = 5 \text{ Hz}$.
Final Answer: (A)
