As per your syllabus, eqn 7.35, the orbital speed of a satellite at height h above Earth's surface is which?
Av = √(2 G M / R)
Bv = G M / (R + h)
Cv = √(G M R)
Dv = √[G M / (R + h)]
Answer & Solution
Correct answer: D. v = √[G M / (R + h)]
syllabus eqn 7.35: orbital speed v = √(GM/(R+h)).
For near-Earth (h=0), v_0 = √(gR) ≈ 7.9 km/s.
