Two particles p and q located at distances r_p and r_q respectively from the centre of a rotating disc such that r_p gt r_q .

Sound from a point isotropic source spreads equally in all directions in homogeneous medium. Therefore its intensity decreases with square of distance from the source. When distance between observer and the source changes, apart from changes in intensity, the observer listens sound of pitch higher or lower than actual pitch depending upon the fact that the distance between the observer and source is decreasing or increasing respectively. An observer O is at a distance 2R from centre of a circle of radius R. A point isotropic sound source S moves on the circle with uniform angular velocity omega = pi//3 " rad"//s . Initially observer, source and centre of the circle are in same line. Sound emitted by the source at two successive instants t_(1) and t_(2) has minimum and maximum observed pitch respectively, then –
