When the area of cross-section of a stretched wire is halved and tension is doubled, the speed of propagation of transverse waves along it becomes \(k\) times the initial speed. Then, \(k\)
- A 1
- B 4
- C 2
- D 8
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
Speed of transverse wave in stretched wire is given as \[ v=\sqrt{\frac{T}{m}} \] where, \(T=\) tension in the wire and \(\quad m=\) mass per unit length of wire.…
