Physics - Sound Wave Question with Solution | TestHub

A detector is revolving in a horizontal circle of radius $\mathrm{R}=2.5\mathrm{m}$ with the help of a massless string as shown in figure with speed 10 m/sec. Source S is emitting sound of frequency 660 Hz and sound velocity in air is $330\mathrm{m}/\sec$. If detector detects a frequency of 680 Hz , then value of x is :-
