The orbital speed of satellite orbiting around the Earth is:
Correct answer: B. √GMe/Re
- A. √GM/Re
- B. √GMe/Re
- C. √GMe/R²
- D. √GMe/h
Explanation
The correct formula to calculate the orbital speed (v) of a satellite orbiting the Earth is: v = √(GMe/r) where G is the gravitational constant, Me is the mass of the Earth, and r is the distance between the center of the Earth and the satellite. To derive this formula, we can start with the centripetal force equation F = m v² / r G (Me * m) / r² = m v² / r Solving for v, we get: v = √(GMe/r)
