Question

Write the definition of an artificial satellite and derive the expression for its orbital velocity and time period of it

Answer 1

Artificial satellite ➡️

artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon

Since centripetal force exert on the orbited body is equal to the gravitational force exert between the two bodies, then

Fc=F

mv2/r=GMm/r2

v2/r=GM/r2

[since m and m do cancel]

w2r=GM/r2.

(since v=wr)

w2=GM/r3

4p2/T2=GM/r3

[where is a radian pie]

T2=r34p/GM

Therefore period T=4p2∗r3/GM−−
