Frequency of tuning fork A is 256 Hz. It produces 4 beats/second with tuning fork B. When wax is applied at tuning fork B then 6 beats/second are heard. Frequency of B is :-

A tuning fork 'P' of frequency 280Hz produces 6 beats/s with unknown tuning fork 'Q'

Tuning fork A of frequency 205 Hz produces 5 beats/sec with another fork B. After filing the tuning fork B, it produces 3 beats/sec with A. What was the frequency of the fork B before filling?

A tuning fork produces 7 beats/s with a tuning fork of frequency 248Hz. Unknown fork is now loaded and 7 beats/s are still heard. The frequency of unknown fork was

A tuning fork produces 7 beats/s with a tuning fork of frequency 248Hz. Unknown fork is now loaded and 7 beats/s are still heard. The frequency of unknown fork was

The frequency of tuning fork A is 2% more than the frequency of a standard tuning fork. The frequency of a tuning fork B is 3% less than the frequency of the same standard tuning fork. If 6 beat/s are heard when the tuning fork A and B are excited , then frequency of A will be

The frequency of tuning fork A is 2% more than the frequency of a standard tuning fork. The frequency of a tuning fork B is 3% less than the frequency of the same standard tuning fork. If 6 beat/s are heard when the tuning fork A and B are excited , then frequency of A will be

A tuning fork 'A' produces 6 beats per second with another fork 'B'. On loading 'B' with a little wax, it produces 5 beats per second with 'A'. If the frequency of 'A'is 256 Hz find the frequency of 'B?.

Tuning fork A of frequency 258 Hz gives 8 beats with a tuning fork B. When the tuning fork A is filed and again A and B are sounded the number of beats heard decreases. The frequency of B is
