A tuning fork produces 4 beats`//`s when sounded with a fork of frequency 512 Hz. The same tuning fork. When sounded with another fork of frequency 514 Hz produces 6 beats `//` second. Find the unknown frequency of the fork.

A tunning fork produces 6 beast/s when sounded with a tuning fork of frequnecy 256 Hz. The same tunning fork when sounded with another tunning fork of frequency 252 Hz produces 2 beat/s. Find the frequency of the tunning fork.

A tuning fork when sounded with tuning fork of frequency 256 produces 4 beats//sec and when sounded with another of frequency 250 produces 2 beats//sec . The frequency of the fork is -

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

A tuning fork A produces 5 beats/sec with another tuning fork B of frequency 256 Hz. If tuning fork A produces 1 beats/sec with some other tuning fork C of frequency 250 Hz, then calculate the frequency of fork A.

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per second. On loading the tuning fork whose frequency is not known and sounded together with a tuning fork of frequency 100 produces one beat, then the frequency of the other tuning fork is

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per second. On loading the tuning fork whose frequency is not known and sounded together with a tuning fork of frequency 100 produces one beat, then the frequency of the other tuning fork is

A tuning fork of unknown frequency x, produces 5 beats per second with a tuning fork of frequency of 250 Hz. The produces 10 beats/second with another tuning fork frequency 265 Hz. The unknow frequency is
