A source is moving along a circle x^(2) + y^(2) =R^(2) with constant speed V_(s) =(330pi)/(6sqrt(3))m/s in clockwise direction direction while on observer is stationary at point (2R,0) with respect to the centre of circle frequency emitted by the source is f [velocity of sound V= 330 m/s] Maximum frequency heard by observer :
