A transverse wave travels on a taut steel wire with a velocity of v when tension in it is 2.06 × 104 N. When the tension is changed to T, the velocity changed to v/2. The value of T is close to :

Multiple Choice Options

  • A 30.5 × 104 N
  • B 2.50 × 104 N
  • C 10.2 × 102 N
  • D 5.15 × 103 N

Step-by-Step Verified Solution

v=Tμ

∴ v1v2=T1T2

v1 = v, v2 = v2

⇒ vv2= 2.06×104T2

⇒ T2 = 2.06×1044 = 5.15 × 103 N
