STANDARD Physics Angular Speed MCQ Question
Two particles A and B are moving in uniform circular motion in concentric circles of radii rₐ and r_b with speed vₐ and v_b respectively. Their time period of rotation is the same. The ratio of angular speed of A to that of B will be
1 : 1
rₐ : r_b
vₐ : v_b
r_b : rₐ
Correct Answer
Detailed Explanation
Since the time periods are the same, Tₐ = T_b. Therefore, 2π/ωₐ = 2π/ω_b, which implies ωₐ : ω_b = 1:1.
