Question

-) An Artificial satellite is revolving around the earth of radius 6400 km takes 10 hours to complete one revolution. Find the distance to it from the surface of the earth. Acceleration due to gravity on the surface of earth is 9.8m/s2.​

Answer 1

Time period of the satellite is given by: T=2π

g

r

Almost close to surface of Earth ⟹r=R

e

∴ Time period, T=2π

9.8

6400×10

3

Time period, T=5077 seconds
