8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
The geostationary orbit of a satellite is at a height above the Earth's surface of about:
Answer: A. 36 000 km
Why: The orbital radius is about 42 000 km, with the satellite's period equal to 24 h.
At a depth d below Earth's surface (d small compared with the radius R, Earth treated as uniform), the acceleration due to gravity is:
Answer: C. g(1 − d/R)
Why: Inside a uniform Earth only the mass within radius (R − d) attracts the body, giving g' = g(1 − d/R).
The escape velocity from the Earth's surface is √2 times the:
Answer: A. orbital velocity of a satellite near the surface
Why: v_e = √(2gR) and v_o = √(gR).
An astronaut in an orbiting satellite feels weightless because:
Answer: B. the astronaut and the satellite are both in free fall with the same acceleration
Why: Gravity is still about 90% of its surface value at typical heights.
When a satellite moves to a higher circular orbit, its orbital speed and its time period:
Answer: C. decrease and increase respectively
Why: v ∝ 1/√r and T ∝ r^(3/2).
The gravitational field at the centre of a uniform ring of mass M is:
Answer: B. zero
Why: The contributions of diametrically opposite elements cancel.
The work needed to take a mass of 1 kg from the Earth's surface to infinity is about:
Answer: A. 6.3 × 10⁷ J
Why: W = GM/R = gR ≈ 6.27 × 10⁷ J.
The time period of a satellite orbiting very close to the surface of a planet of uniform density ρ is:
Answer: A. √(3π/Gρ), independent of the radius of the planet
Why: T = 2π√(R³/GM) with M = (4/3)πR³ρ.
