Question

two cars A and B are going around concentric circular path of radii Ra and Rb respectivelly if the two cars complete the cicular path in the same time then ratio of angular speed of A and B is
​

Answer 1

Explanation:

The radii of two concentric circles are 7 cm and 14 cm respectively. The area .... Two cars A and B accelerate in the ratio of 2: 3 respectively. .... rA = 2rB, vA = 4 m/s, vB = 3 m/ s.

Answer 2

Ratio of their speeds:-

The angular speeds are the same because both cars cover 360° (or if you prefer, 2π radians) in the same time.

So the ratio is 1:1

So A/B=1/1

Speed:-

The radii of two concentric circles are 7 cm and 14 cm respectively.

Two cars A and B accelerate in

the ratio of 2: 3 respectively.

rA = 2rAB

vA = 4 m/s

vB = 3 m/ s.
