MCQ
A uniform rope having some mass hanges vertically from a rigid support. A transverse wave pulse is produced at the lower end. The speed $(v)$ of the wave pulse varies with height $(h)$ from the lower end as:
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
c
$v=\sqrt{\frac{T}{\mu}}=\sqrt{\frac{\mu x g}{\mu}}=\sqrt{g x} \Rightarrow v^{2}=g x$
$v=\sqrt{\frac{T}{\mu}}=\sqrt{\frac{\mu x g}{\mu}}=\sqrt{g x} \Rightarrow v^{2}=g x$
