प्रश्न
An artificial satellite is moving in a circular orbit of radius nearly 42,250 km. Calculate its linear velocity, if it takes 24 hours to revolve round the earth

उत्तर
Radius of orbit is 42250 km.
Distance covered by satellite to complete 1 revolution is 2 πr.
So distance is = 2 X 3.14 X42250 =265330 km.
time taken by satellite to complete one revolution is 24 hr = 24X60X60=86400 sec.
so linear velocity is= distance /time= 265330/86400 ms-1 = 3.07 km s-1.
