Two particles describe the same circle of radius R in the same direction with the same speed V. then at the given instant relative angular velocity of 2 with respect to 1 will be :

Question

G1 Physics · Accepted Answer

The separation of the particles is 2R sin(θ/2), while their relative speed is 2v sin(θ/2). Therefore the angular speed of particle 2 about particle 1 is [2v sin(θ/2)]/[2R sin(θ/2)]=v/R. Hence C.
