Question
Two strings
and
of a sitar produce a beat frequency
When the tension of the string
is slightly increased the beat frequency is found to be
If the frequency of
is
then the original frequency of
was
- 296 Hz
- 298 Hz
- 302 Hz
- 302 Hz
The correct answer is: 296 Hz

beat frequency
which is decreasing
after increasing the tension of the string 
Also tension of wire
increasing so 
Hence
