Question

Two racing cars of masses m and 4m move in circles of radii r and 2r and each completes one revolution in the same time. Find ratio of angular speeds of the first and second cars.

G1 Physics · Accepted Answer

Angular speed ω=2π/T. Both cars have identical revolution period T, regardless of masses or radii. Hence ω₁/ω₂=1 and ratio is 1:1. Answer: D.
