Question

a bunny is resting next to a house. what is the correct relationship of forces acting between the bunny and the house?

Explanation:

Step1: Analyze the situation

The bunny is at rest next to the house. There is no horizontal interaction force between them as the bunny is just resting beside and not pushing or pulling the house horizontally. The main interaction is vertical. The bunny exerts a downward - force (its weight) on the ground near the house, and the ground exerts an upward normal force on the bunny. The house also exerts a downward force (its weight) on the ground and the ground exerts an upward normal force on the house. But between the bunny and the house directly, there is no significant vertical interaction force either in a non - contact situation. However, if we consider the gravitational force, every object with mass attracts every other object with mass. But this gravitational force between the bunny and the house is extremely small and negligible in this context. The most relevant forces here are the normal and weight - like forces in the vertical direction. Since the bunny is on the ground near the house, the vertical forces are the ones to consider for the relationship between them.

Step2: Identify the force direction

The vertical forces are the ones that are relevant for the bunny - house relationship in this case. The bunny's weight acts downwards and the normal force from the ground on the bunny acts upwards. The house also has its own weight acting downwards on the ground and the ground exerts an upward normal force on it. But between the bunny and the house directly, there is no significant force interaction in the horizontal direction and the only possible interaction is in the vertical direction where the forces are in the up - down direction.

Answer:

The third option (the one with vertical up - down arrows)
