Orbital VelocityHardQuestion 6233

Question

A satellite at height h above Earth. Orbital speed v₀ compared to surface orbital speed:
  1. A
    v₀ = √(gR²/(R+h))
    Correct
  2. B
    v₀ = √(gR)
  3. C
    v₀ = g(R+h)
  4. D
    v₀ = √(gR/(R+h))

Correct answer

v₀ = √(gR²/(R+h))

Explanation

v₀ = √(GM/(R+h)) = √(gR²/(R+h)) = √(gR²/(R+h)).
