Question 1
Two point masses m1 = 1000 kg and m2 = 4000 kg are separated by a distance of r = 2.0 m in a vacuum. Using Newton's Law of Universal Gravitation (G = 6.674 x 10^-11 N m^2/kg^2), what is the magnitude of the gravitational force between them?
Correct Answer:
6.67 x 10^-5 N
Question 2
A spherical planet has mass M = 6.00 x 10^24 kg and radius R = 6.00 x 10^6 m. Using G = 6.674 x 10^-11 N m^2/kg^2, what is the surface gravitational field strength g?
Correct Answer:
11.1 N/kg
Question 3
What is the weight of an astronaut with mass m = 70.0 kg on the Moon's surface, where local gravitational acceleration is g_moon = 1.62 m/s^2?
Correct Answer:
113 N
Question 4
Two point charges q1 = +2.00 μC and q2 = +5.00 μC are separated by d = 0.100 m in air (k_e = 8.99 x 10^9 N m^2/C^2). What is the magnitude of the electrostatic repulsive force between them?
Correct Answer:
8.99 N
Question 5
What is the electric field magnitude E at distance r = 0.200 m from a point charge q = +4.00 nC in a vacuum (k_e = 8.99 x 10^9 N m^2/C^2)?
Correct Answer:
899 N/C
