STANDARD Physics Orbital Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Two satellites of Earth S₁ and S₂ are moving in the same orbit. The mass of S₁ is four times the mass of S₂. Which one of the following statements is true?
A
The potential energies of satellite in the two cases are equal.
B
S₁ and S₂ are moving with the same speed.
C
The kinetic energy of S₁ is four times that of S₂.
D
The total energy of S₁ is four times that of S₂.
Correct Answer
Option B
Detailed Explanation
In the same orbit, the speed of a satellite depends only on the gravitational constant and the radius of the orbit, not on the mass of the satellite. Therefore, both S₁ and S₂ have the same speed.
