An artificial satellite is moving in a circular orbit of radius 42,250 km. Calculate its speed if it takes 24 hour to revolve around the earth.

Text Solution

Verified by Experts

Here,` r = 42,250 km = 42250 xx 1000 m `
Time taken for one rovolution
`= 24 h = 24 xx 60 xx 60 s`
Speed (u) `= ("Distance")/("Time") = (2pi r )/("Time") = (2 xx (22)/(7) xx 42250 xx 1000 m )/( 24 xx 60 xx 60 s) `
`~~3073.74 ms ^(-1)`
The speed of the satellite is `3073.73 ms ^(-1)`

An artificial satellite is revolving around a planet of mass M and radius R in a circular orbit of radius r. From Kepler's third law about the period of a satellite around a common central body, square of the period of revolution T is proportional to the cube of the radius of the orbit r. Show using dimensional analysis that T=(k)/(R) sqrt((r^(3))/(g)) where k is dimensionless RV g constant and g is acceleration due to gravity.
