A uniform metal wire has length 'L', mass 'M' and density ' Q '. It is under tension 'T" and ' v^ is the speed of transverse wave along the wire. The area of cross-section of the wire is

Options

  1. Av ² T
  2. BT v ²
  3. CT ² v
  4. DTv ²

Correct answer

B. T v ²

Step-by-step solution

( C ) aligned V &= T m aligned [ m = M L = AL L = A ] V = T A V ²= T A A = T V ²
