A transverse wave travels on a taut steel wire with a velocity of when tension in it is `2.06xx10^4 N` . When the tension is changed to T, the velocity changed to 3v. The value of T is close to :

A

`10.2 xx10^2 N`

B

`5.15 xx10^3 N`

C

`2.50xx10^4 N`

D

`18.54 xx10^4 N`

Text Solution

Verified by Experts

The correct Answer is:
D
Velocity of transverse wave `V prop sqrtT`
`V to 3V rArr T to T' = 9T` < br> `T' 2.06xx10^4 xx9=18.54 xx10^4 N`
