The fundamental frequency of a stretched...

The fundamental frequency of a stretched string is `V_(0)`. If the length is reduced by `35%` and tension increased by `69%` the fundamental frequency will be

A

`0.2V_(0)`

B

`0.5V_(0)`

C

`2.0V_(0)`

D

`1.6V_(0)`

Text Solution

Verified by Experts

The correct Answer is:
C
`v_(0)=1/(2L)sqrtT/M` Frequency is new cond. `v = 1/(2(65% of L))(sqrtT+69%of T)/M`
