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 wave length received observer

Answer»

`(SQRT(3) + npi)V/f`
`(6+PI)/6 V/f`
`(6sqrt(3)-pi)/(6sqrt(3))V/f`
`((6sqrt(3) + pi)/(6sqrt(3)))V/f`
