Question

A source is moving along a circle given by the equation x2 + y2 = R2, with cons†an t speed , in anti-clockwise sense. A detector is at rest at point (2R, 0) w.r.t. the centre of the circle. If the frequency emitted by the source is f and the speed of sound, C = 330 m/s. Then a) The position of the source when the detector records the maximum frequency is b) The coordinate of the source when the detector records minimum frequency is c) The maximum frequency recorded by the detector is d) The minimum frequency recorded by the detector is
