The gravitational force between which two objects would be the most difficult to notice? a. the moon and the earth b. the moon and a water particle c. the earth and the sun d. a water particle and an air particle

d. A water particle and an air particle

Explanation:

The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:

where G is the gravitational constant

This force is therefore, directly proportional to the masses and inversely related to the distance between them.

Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.

answer; i do believe the correct answer is (river); /// good luck

am i too late?
