Two cars \(A\) and \(B\) are going around concentric circular paths of radii \(R_A\) and \(R_B\). If the two cars complete the circular paths in the same time, then the ratio of angular speed of \(A\) and \(B\) is
- A \(1: 1\)
- B \(R_A: R_B\)
- C \(R_B: R_A\)
- D \(1: 2\)
Answer & Solution
Correct Answer
(A) \(1: 1\)
Step-by-step Solution
Detailed explanation
Angular speed of a body moving on circular path is given as \[ \omega=\frac{2 \pi}{T} \] where, \(T\) is the time-period. \(\therefore \quad \frac{\omega_A}{\omega_B}=\frac{T_B}{T_A}\) Given, \(\quad T_A=T_B\)…
