In the diagram shown below, both the strings A B and C D are made of same material and have same cross-section. The pulleys are light and fictionless. If the speed of wave in string A B is v₁ and in C D is v₂ , then v₁ v₂ is

Options

  1. A1
  2. B2
  3. C2
  4. D1 / 2

Correct answer

D. 1 / 2

Step-by-step solution

Let the speed of wave in string be v and tension in string be T . gathered v T v_ A B v_ C D = T 2 T = 1 2 gathered
