Two wires A and B are of same length, redius and same material are in unison. If tendion in A is increassed by 4% 4 beats are heard, then the frequency of the note produced when they ware in unison, will be

A

50 Hz

B

100 Hz

C

150 Hz

D

200 Hz

Text Solution

Verified by Experts

The correct Answer is:
D

`(104)/(100)=((n+4)/(n))^(2)or sqrt((104)/(100))= (n+4)/nrArrn=200 Hz`
