Answer to Problem 7C
The gravitational force from the Sun on the Moon is about
Explanation of Solution
According to Newton’s law of gravitation; gravity is a force between two bodies having masses which causes the attraction between them, and it is directly proportional to product of mass of bodies and inversely proportional to square of the distance between them.
Write the expression for gravitational force.
Here,
Compare gravitational acceleration on Earth and station.
Here,
