  1. Question 1

    Q1. What is the minimum velocity required for a satellite to orbit the Earth at an altitude of 200 km?

    • A) 7.8 km/s
    • B) 7.5 km/s
    • C) 7.2 km/s
    • D) 7.0 km/s

    Answer: 7.8 km/s

    Explanation: The orbital velocity is given by v = √(G * M / (R + h)) = √(g * R² / (R + h)), v ≈ 7.8 km/s.
