Solution

The correct option is D $306 H z$
$\begin{matrix} (f + \frac{2}{100} f) - f = 6 \Rightarrow \frac{2 f}{100} = 6 \Rightarrow f = 300 H z ∴ f r e q u e n c y o f A i s = f + \frac{2}{100} f = 306 H z \end{matrix}$
Hence,
option $(D)$ is correct answer.

The frequency of a tuning fork A is 2% greater than that of the standard tuning fork. These tuning forks produce 6 beat/s. The frequency of A is

The correct option is D 306Hz(f+2100f)−f=6⇒2f100=6⇒f=300Hz∴frequencyofAis=f+2100f=306HzHence,option (D) is correct answer.

The frequency of a tuning fork $A$ is $2$ % greater than that of the standard tuning fork. These tuning forks produce $6$ beat/s. The frequency of $A$ is

The correct option is D $306 H z$
$\begin{matrix} (f + \frac{2}{100} f) - f = 6 \Rightarrow \frac{2 f}{100} = 6 \Rightarrow f = 300 H z ∴ f r e q u e n c y o f A i s = f + \frac{2}{100} f = 306 H z \end{matrix}$
Hence,
option $(D)$ is correct answer.
