Question : An artificial satellite is moving in a circular orbit of radius 42250 km. calculate its speed if it takes 24 hours to revolve around the Earth?
Answer :
Radius Of the orbit : 42250 km ( Given )
The Distance that is covered in one revolution : 2πr
( Circumference of The Orbit )
= 2 ×× 42250
= 265571.43 km.
Time taken in one revolution = 24 h, One day.
Therefore, Speed of satellite =
=
= 11065.48 km/h.
