A source of sound is moving along a circular orbit of radius 3m with angular velocity of 10 rad/s. A sound detector for away from the source is executing linear S.H.M. with frequency `5/pi `Hz along the line Bd with an amplitude BC=CD=6m. The source is at the point A when the sound wave of frequency 340 Hz is produced. At t=0 the position of source is shown. Find the maximum and the minimum frequencies recorded by the detector .(velocity of sound in air =330 m/s)

A

255 Hz, 442 Hz

B

250 Hz, 450 Hz

C

442 Hz, 255 Hz
