gravitation

JEE Main 2015 Sample Questions › Mechanics questions › gravitation

If a satellite is moving in a circular orbit with an angular speed equal to that of the earth and it is directly above the north pole Find the time taken to come over the equatorial plane

I have got the radius of the orbit and hence the time period(T)
But to calculate the time asked in the question which is correct t=T/2 or t=T/2

Please explain it

If I have understood ur question correctly ...

I think it should be t=T/4

bcos T will be the time to get back to the north pole

T/2 will be the time to reach the south pole
