The period of a satellite in a circular ...

The period of a satellite in a circular orbit of radius R is T.The period of another satellite in circular orbit of radius 4R is:

A

4T

B

`(T)/(4)`

C

8T

D

`(T)/(8)`

Text Solution

Verified by Experts

The correct Answer is:
C
`(T_(2)^(2))/(T_(1)^(2))=(r_(2)^(3))/(r_(1)^(3)) rArr T_(2)=T_(1)((4R)/(R ))^((3)/(2)) =8T_(1)`
So the correct choice is (c ).
