Question

Orbits of Artificial Satellites
All artificial satellites do not revolve in similar orbits around the earth. The functions
of the satellite decide the height of the satellites orbit from the carth's surface, the nature
of the orbit (circular/elliptical) and whether the orbit shall be parallel to cquator or making
some angle with it. To put the satellite in its proper orbit at specific height above the
carth's surface, the satellite is taken to that height using a satellite launcher. Then the
satellite is given a specific velocity known as the critical velocity (v) in a tangential
direction to the orbit (fig 10.3). The satellite
then starts revolving around the earth. The
Satellite
formula for the velocity v can be derived as
below
Satellite's
orbit
If a satellite of mass 'm' is revolving
around the carth in an orbit of height 'h' with
speed 'V', then as seen in the chapter on
'Gravitation', a centripetal force my? will
act on it.

Here, 'r' is the orbital radius of the satellite
from the centre of the earth.
