The block of mass m 0 = μ L is attached to a uniform string of mass M = μ L and length L as shown in the figure. If a wave pulse is produced near the block, then the time it takes to reach the ceiling is

Options

  1. A2 - 1 L g
  2. B2 2 + 1 L g
  3. C2 2 - 1 L g
  4. D2 + 1 L g

Correct answer

C. 2 2 - 1 L g

Step-by-step solution

At x position tension in string T = m o g + μ x g V = T μ = L + x g ∫ o t d x L + x g = ∫ o t d t T = 2 2 - 1 L g
