A string of linear mass density $0.01$ kg/m is stretched with a tension of $100$ N. The speed of transverse waves on it is
Answer: (A) $100$ m/s
Concept. Transverse wave speed on a string: $v = \sqrt{\dfrac{T}{\mu}}$.
Step 1. Substitute.
$$v = \sqrt{\frac{100}{0.01}} = 100\ \text{m/s}$$
Answer. $100$ m/s (Option A).
