Two satellite A and B are travelling in ...

Two satellite A and B are travelling in the same plane and same sense in circular orbit around the earth at an atitude `r_(A)` and `r_(B)` from the centre of the earth respectively. If at time `t=0` the satellite are aligned as shown in the figure, knowing that the radius of the earth `R`. Determine the time at which again the satellite will be aligned as they were at `t=0`

Text Solution

Verified by Experts

The correct Answer is:
`2pi((+r_(A)r_(B))^(3//2))/(sqrt(gR)(r_(B)^(3//2)-r_(A)^(3//2)))`
