Two satellites A and B go around a planet in circular orbits of radii 4 R and R respectively. If the speed of the satellite A is 3 V, then the speed of the satellite B will be

`(3v)/2`

`(4v)/2`

12v

Text Solution

Verified by Experts

The correct Answer is:

`(v_B)/(v_A)=sqrt((r_A)/(r_B))=sqrt((4R)/R)rArrv_B=6v`
