A source is moving along a circle `X^2 + Y^2 = R^2` with constant speed `V_s = (330pi)/(6 sqrt3)`m/s in clockwise 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

Options

A. `(R/2, R/2) (R/2, -R/2)`
B. `(R/2, (sqrt(3)R)/2)(R/2, -(sqrt(3)R)/2)`
C. `((sqrt(3)R)/2, (sqrt(3)R)/2)((sqrt(3)R)/2, -sqrt(3)/2)`
D. `((sqrt(3)R)/2, R/2) (0, -R)`

Answer

D
