You are pushing three equal boxes, 8kg each, with a force of 250 on the first.

What is the magnitude of the force of the first box on the second box?

_________N

What is the magnitude of the force of the third box on the second?

_________N

To calculate the magnitude of the force of the first box on the second, we need to consider Newton's third law, which states that every action has an equal and opposite reaction. So, if you are pushing the first box with a force of 250 N, the first box pushes back on you with an equal force of 250 N.

Since the boxes are equal in weight and you are pushing them equally, the force between the first and second box is equal to the force you applied, which is 250 N.

Therefore, the magnitude of the force of the first box on the second is 250 N.

Now, let's move on to the second part of the question.

To calculate the magnitude of the force of the third box on the second, we need to consider that the force applied to the second box by the first box is also exerted on the third box. This is due to the third law of motion.

Since the second box experiences a force of 250 N from the first box, it exerts an equal and opposite force of 250 N on the third box.

Therefore, the magnitude of the force of the third box on the second is also 250 N.

To determine the magnitude of the force exerted by the first box on the second box, we can use Newton's third law which states that "for every action, there is an equal and opposite reaction." This means that the force exerted by the first box on the second is equal in magnitude but opposite in direction to the force exerted by the second box on the first.

Since the force exerted by the first box on the second is 250 Newtons, the magnitude of the force exerted by the second box on the first is also 250 Newtons.

Now, if the second box is experiencing an equal and opposite force from the first box, it will also exert a force of the same magnitude on the third box. So, the magnitude of the force exerted by the third box on the second box would also be 250 Newtons.
