Velocity of a wave in a wire is v when tension in it is `2.06 × 10^4 N`. Find value of tension in wire when velocity of wave become `v/2`.

A

`10.2xx10^(2)N`

B

`5.15 xx10^(3)N`

C

`2.50 xx10^(4)N`

D

`18.54xx10^(4)N`

Text Solution

Verified by Experts

The correct Answer is:
D
Velocity of transverse wave `V prop sqrtT`
`V rarr 3V implies T - T. =9T`
`T. = 2.06 xx10^(4) xx9=18.54 xx10^(4)N`
