Two moving particles P and Q are 10m apart at a certain instant. The velocity of P is 8m/s making an angle of 30° with the line joining P and Q and Q is moving with 6m/s making an angle of 30° with PQ as shown in figure. Then angular velocity of P with respect to Q is

Question

G1 Physics · Accepted Answer

The relative angular speed is the transverse relative speed divided by separation. The transverse components are opposite, so v⊥,rel=8sin30°+6sin30°=7 m/s. Hence ω(rel)=7/10=0.7 rad/s, so D.
