Question

A tuning fork of unknown frequency gives 4 beats/s. With another fork of frequency 310 Hz, it gives the

Answer 1

hey mate here is your answer

Answer 2

314 Hz. In this question, we have to find out the unknown frequency.

We assume here to be the unknown frequency as 'f'.

Therefore, before filling, f - 310 = 4 Hertz, which gives the value of 'f' as 314 Hertz.

After the filling, we can make the equation to read as 310 - f = 4 Hertz.

Hence, the value of 'f' in that case would be 306 Hertz.

Therefore, the needed value of frequency in the question is 314 Hertz.
