- period of revolution is greater than the period of rotation of the earth about its axis
- period of revolution is less than the period of rotation of the earth about its axis
- period of revolution is equal to the period of rotation of the earth about its axis
- mass is less than the mass of earth
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The period of revolution of a synchronous relay satellite is equal to the period of rotation of earth about its axis. This makes it possible to reflects $TV$ signals and transmits $TV$ programmer from one part of the world to the other.

Concepts Used:
Gravitation
In mechanics, the universal force of attraction acting between all matter is known as Gravity, also called gravitation, . It is the weakest known force in nature.
Newton’s Law of Gravitation
According to Newton’s law of gravitation, “Every particle in the universe attracts every other particle with a force whose magnitude is,
- F ∝ (M1M2) . . . . (1)
- (F ∝ 1/r2) . . . . (2)
On combining equations (1) and (2) we get,
F ∝ M1M2/r2
F = G × [M1M2]/r2 . . . . (7)
Or, f(r) = GM1M2/r2
The dimension formula of G is [M-1L3T-2].
