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] The cooridnates of source when observer records the jpaximum and minimum frequency

Answer»

`(R/2, R/2) (R/2, -R/2)`
`(R/2, (sqrt(3)R)/2)(R/2, -(sqrt(3)R)/2)`
`((sqrt(3)R)/2, (sqrt(3)R)/2)((sqrt(3)R)/2, -sqrt(3)/2)`
`((sqrt(3)R)/2, R/2) (0, -R)`
