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

Options

  1. A1: 1
  2. BR_A: R_B
  3. CR_B: R_A
  4. D1: 2

Correct answer

A. 1: 1

Step-by-step solution

Angular speed of a body moving on circular path is given as = 2 T where, T is the time-period. _A _B = T_B T_A Given, T_A=T_B _A _B = T_A T_A _A _B = 1 1 _A: _B=1: 1
