A and B are two satellite revolving around the earth in circular orbits with radii `R_(A) and R_(B)`. Their periods `T_(A) and T_(B)` are 8 h and 1 h
A and B are two satellite revolving around the earth in circular orbits with radii `R_(A) and R_(B)`. Their periods `T_(A) and T_(B)` are 8 h and 1 h respectively. Then the ratio of `(R_(A)//R_(B))` is equal to
A. 4
B. 8
C. `(8)^(1//3)`
D. `sqrt8`

Correct Answer - a
`(R_(A))/(R_(B))=((T_(A))/(T_(B)))^(2//3)=((8)/(1))^(2//3)`
`(R_(A))/(R_(B))=4.`
