Question

a snowflake falls to the ground. what is the correct relationship of forces acting between the snowflake and the earth?

Explanation:

Step1: Recall Newton's third - law

According to Newton's third - law, for every action, there is an equal and opposite reaction. The force of the Earth on the snowflake (gravitational force pulling the snowflake downwards) and the force of the snowflake on the Earth (an equal - magnitude but opposite - direction gravitational force) are an action - reaction pair.

Answer:

The force of the Earth on the snowflake and the force of the snowflake on the Earth are equal in magnitude and opposite in direction. The correct arrow representation is the one with two arrows pointing towards each other along the vertical line connecting the snowflake and the Earth (the third option among the ones shown in the picture, assuming the third one has vertical, opposite - direction arrows).
