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?

Turning fork A of frequency 305 Hz produces 5 beats s^(-1) with another turing fork B. After filling tuning fork B, it produces 3 beats s^(-1) with A. The frequency of B before filling was

Turning fork A of frequency 305 Hz produces 5 beats s^(-1) with another turing fork B. After filling tuning fork B, it produces 3 beats s^(-1) with A. The frequency of B before filling was

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

Tuning fork A has frequency 256 Hz. It produces 4 beats per second with fork B. When the prongs of fork B are rubbed little, it produces 2 beats per second with A. Find out frequencies of foek B, before and after rubbing its prongs.

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 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 A of unknown frequency produces 5 beats/s with a fork of known frequency 340 Hz. When fork A is filed, the beat frequency decreases to 2 beats/s. What is the frequency of fork A ?

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?.
