What is a period of revolution of the earth satellite?
Ignore the height of satellite above the surface of the earth. Given,
(i) the value of gravitational acceleration, g = 10 ms -2.
(ii) radius of the earth, Re = 6400 km
(Take, = 314) [KCET 2014]
Given, Re = 6400 km:: 6.4 X 106m, =3.14, 9 =10 ms-2
We know that, the period of revolution of the earth satellite
= 83.73 min
