A tuning fork 'P' of frequency `280Hz` produces `6` beats/s with unknown tuning fork 'Q'

A

`{:(A,B,C,D),(Q,R,S,R):}`

B

`{:(A,B,C,D),(Q,R,Q,P):}`

C

`{:(A,B,C,D),(P.Q,Q.R,R.S,P):}`

D

`{:(A,B,C,D),( R.S,Q.R,S,R):}`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(p)=280`, `n_(q)=274`, or `286` by waxing frequency decrease and by filing frequency increase.
