The extension in a string, obeying Hooke's law, is x. The speed of sound in the stretched string is v. If the extension in the string is increased to `1.5 x`, the speed of sound will be :-

A

`1.22V`

B

`0.61V`

C

`1.50V`

D

`0.75V`

Text Solution

Verified by Experts

The correct Answer is:
A
`V=sqrt((T)/(mu))` (but`T=(yAe)/(l))impliesV prop sqrt(e )`
