Wave Mechanics Question 647

Question: Two strings A and B, made of same material, are stretched by same tension. The radius of string A is double of radius of B. A transverse wave travels on A with speed $ V _{A} $ and on B with speed Vo. The ratio $ V _{A}/V _{B} $ is

Options:

A) 1/2

B) 2

C) 1/4

D) 4

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $ \frac{V _{A}}{V _{B}}=\frac{D _{B}}{D _{A}}=\frac{1}{2} $
