A uniform rope of mass \(0.1 \mathrm{~kg}\) and length \(2.45 \mathrm{~m}\) hangs from a rigid support. The time taken by the transverse wave formed in the rope to travel through the full length of the rope is (Assume \(g=9.8 \mathrm{~m} / \mathrm{s}^2\) )
- A \(0.5 \mathrm{~s}\)
- B \(1.6 \mathrm{~s}\)
- C \(1.2 \mathrm{~s}\)
- D \(1.0 \mathrm{~s}\)
Answer & Solution
Correct Answer
(D) \(1.0 \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
The time taken by the transverse wave \(t=2 \sqrt{\frac{l}{g}}=2 \sqrt{\frac{2.45}{9.8}}=1 \mathrm{~s}\)
