A source emitting sound is tied to one end of a string of length 50‌cm and is rotated with an angular speed of 40‌rad‌ s−1 in the horizontal plane. The ratio of the maximum and minimum frequencies of the sound heard by an observer standing at a distance of 10m from the fixed end of the string is (speed of sound in air =340ms−1 )
