Question

An artificial satellite is moving in a circular orbit of radius 4200 km. What is its speed if it takes 24 hours to revolve around the earth?

Answer 1

Let us assume an artificial satellite, which is moving in a circular orbit of radius 42250 km covers a distance ‘s’ as it revolve around earth with speed ‘v’ in given time ‘t’ of 24 hours.= 42250

Radius of circular orbit r

Time taken by artificial satellite t=24 hours

Distance covered by satellite s =Circumference of circular orbit

 Speed of satellite v

= 3.073 km/s
