Question

Fundamental frequency of sonometer wire is n. If the length, tension and diameter of wire are tripled, the new fundamental frequency is :

• A. $\frac{n}{\sqrt{3}}$
• B. $\frac{n}{3}$
• C. $n\sqrt{3}$
• D. $\frac{n}{3\sqrt{3}}$

Answer 1

The correct option is D $\frac{n}{3\sqrt{3}}$

Hence, the option $D$ is the correct answer.
