Explain how the magnitude of the gravitational force between the earth and the sun changes as the earth moves from position 'A'
Lina20 [59]

Answer:

Explanation:

We are not told where A and B are, but I'll assume that they are two points on the orbit of earth about the sun.

As that orbit is an ellipse, the two points likely do not have the same distance between the earth and sun.

As gravity varies with the inverse of the square of the distance (F = GMm/d²), the force at the closer distance will be greater than the force at the longer distance.
