Question 1

Two point masses m1 = 600 kg and m2 = 1200 kg are separated by a distance r = 3.0 m in a vacuum. Using Newton's Law of Universal Gravitation (G = 6.67 x 10^-11 N m^2/kg^2), what is the magnitude of the gravitational attraction between them?

5.34 x 10^-6 N 1.60 x 10^-5 N 2.67 x 10^-6 N 4.80 x 10^-5 N

Correct Answer:

5.34 x 10^-6 N

Question 2

If the acceleration due to gravity at Earth's surface is g0 = 9.80 m/s^2, what is the magnitude of the gravitational field intensity g at an altitude h = 2 R_E above Earth's surface (where R_E is Earth's radius)?

3.27 m/s^2 1.09 m/s^2 2.45 m/s^2 4.90 m/s^2

Correct Answer:

1.09 m/s^2

Question 3

What is the gravitational potential V at a point located at distance r = 3 R_E from Earth's center? (Use Earth mass M_E = 5.97 x 10^24 kg, R_E = 6.37 x 10^6 m, G = 6.67 x 10^-11 N m^2/kg^2).

-6.25 x 10^7 J/kg -3.13 x 10^7 J/kg -2.08 x 10^7 J/kg -1.04 x 10^7 J/kg

Correct Answer:

-2.08 x 10^7 J/kg

Question 4

Calculate the work done by the gravitational force when moving a mass m = 200 kg from Earth's surface (r1 = R_E) to a distance r2 = 2 R_E from Earth's center.

-6.25 x 10^9 J +6.25 x 10^9 J -1.25 x 10^10 J +3.13 x 10^9 J

Correct Answer:

-6.25 x 10^9 J

Question 5

A satellite orbits Earth in a circular path at an altitude h = 1000 km above the surface. What is its orbital speed? (M_E = 5.97 x 10^24 kg, R_E = 6370 km, G = 6.67 x 10^-11 N m^2/kg^2).

7.91 km/s 6.45 km/s 8.24 km/s 7.35 km/s

Correct Answer:

7.35 km/s
