An artificial satellite is moving in a circular orbit of radius 42250Km. Calculate its speed if it takes 24 hours to revolve around the earth.

Text Solution

Verified by Experts

Radius of the circular orbit, r= 42250Km. Time take to revolve around the earth, t=24h
Speed of a circular moving object `v= (2pi r)//t = [2 xx (22//7) xx 42250 xx 1000]//(24xx 60 xx 60)`
`=(2 xx 22 xx 4225 xx 1000)//(7 xx 24 xx 60 xx 60) ms^(-1)`
`=3073.74 ms^(-1)`
