1.	Wire having tension 225 N produces six beats per second when it is tuned with a fork. When tension changes to 256 N, it is tuned with the same fork, the number of beats remain unchanged. The frequency of the fork will beA. 186 HzB. 225 HzC. 256 HzD. 280 Hz
Answer» Correct Answer - A `T_(1)=225N,T_(2)=256N` `n_(2)-n=6" "n_(2)gtngtn_(1)` `(n-n_(1)=6)/(n_(2)-n_(1)=12)` `(n_(2))/(n_(1))=sqrt((T_(2))/(T_(1)))=sqrt((256)/(225))=(16)/(25)` `(n_(2)-n_(1))/(n_(1))=(16-15)/(15)` `(12)/(n_(1))=(1)/(15)` `n_(1)=180Hz " "n=n_(1)+6` `n=180+6` =186 Hz
