The radii of circular orbits of two satellite `A` and `B` of the earth are `4R` and `R`, respectively. If the speed of satellite `A` is `3v`, then the speed of satellite `B` will beA. 3v/4B. 6vC. 12vD. 3v/2

The radii of circular orbits of two satellite `A` and `B` of the earth

1.	The radii of circular orbits of two satellite `A` and `B` of the earth are `4R` and `R`, respectively. If the speed of satellite `A` is `3v`, then the speed of satellite `B` will beA. 3v/4B. 6vC. 12vD. 3v/2
Answer» Correct Answer - B speed of satellite `V=sqrt((GM)/(r ))` `implies (V_(B ))/(V_(A))=sqrt((r_(A))/(r_(B))=sqrt((4R)/(R ))=2` `implies V_(B)=(3v)(2)=6v`
