MCQ
The fundamental frequency of a sonometer with a weight of $4\,kg$ is $256\,Hz$ . The weight required to produce its octave is .... $kg-wt$
- A$4$
- B$12$
- ✓$16$
- D$24$
✓
Answer
Correct option: C.
$16$
c
The octave has double frequency. Hence, the force should be $4$ times the initial value, i.e., $16\,kg-wt$
