Question

The time period of a satellite depends on _____

(a) the mass of the satellite

(b) radius of its orbit

(c) both mass of satellite and radius of the orbit

(d) neither mass of satellite nor radius of the orbit

I have been asked this question in semester exam.

I need to ask this question from Gravitation topic in division Gravitation of Physics – Class 11

Answer 1

Correct option is (b) radius of its orbit

Easy explanation: The time period of a satellite is given by;

T = 2 x pi x [(R + h)^3 / (G X M)]^1/2

Where;

R = Radius of planet

h = Height above the planet

M = Mass of the planet

(R+h) = Radius of orbit
