Question 1
A satellite orbits Earth at an altitude equal to Earth's radius $R_E = 6.37 \times 10^6\text{ m}$. If the gravitational field strength at Earth's surface is $g_0 = 9.80\text{ m/s}^2$, what is the gravitational field strength $g$ at the satellite's orbital altitude?
Correct Answer:
2.45 m/s²
Question 2
According to Kepler's Third Law ($T^2 / a^3 = k$), if Planet A orbits a star at distance $r$ with orbital period $T$, what is the orbital period of Planet B orbiting the same star at a distance of $4r$?
Correct Answer:
8T
Question 3
What is the escape velocity from the surface of a spherical planet with mass $M = 6.0 \times 10^{24}\text{ kg}$ and radius $R = 6.4 \times 10^6\text{ m}$? ($G = 6.67 \times 10^{-11}\text{ N}\cdot\text{m}^2/\text{kg}^2$)
Correct Answer:
1.12 × 10⁴ m/s
Question 4
The gravitational potential at a point outside a planet of mass $M = 4.0 \times 10^{24}\text{ kg}$ is $V = -4.0 \times 10^7\text{ J/kg}$. What is the distance $r$ from the center of the planet to this point? ($G = 6.67 \times 10^{-11}\text{ N}\cdot\text{m}^2/\text{kg}^2$)
Correct Answer:
6.67 × 10⁶ m
Question 5
A space probe of mass $m = 500\text{ kg}$ moves in a circular orbit of radius $r = 1.0 \times 10^7\text{ m}$ around a body of mass $M = 5.0 \times 10^{24}\text{ kg}$. What is its orbital speed? ($G = 6.67 \times 10^{-11}\text{ N}\cdot\text{m}^2/\text{kg}^2$)
Correct Answer:
5.77 × 10³ m/s
