A tuning fork gives

5

beats with another tuning fork of frequency

100\,\,Hz.

When the first tuning fork is loaded with wax, then the number of beats remains unchanged, then what will be the frequency of the first tuning fork

View answer and explanation

Correct option: C

105\,\,Hz

Option C (

105\mathrm{ }Hz

) is correct because adding wax decreases the frequency of the tuning fork, and since the number of beats remained the same, the original frequency must have been higher than 100 Hz.
