A string is taken and stretched so that it elongates by 2% . Then its fundamental frequency

A

Increase by 2%

B

Increase by 1%

C

Decrease by 2%

D

Decrease by 1%

Text Solution

Verified by Experts

The correct Answer is:
C
`n_2/n_1 = l_1/l_2`
`therefore n_2 = 100/102 n_1 = 98% n_1` = decreases by 2%
