A 5 kg magnet exerts a constant force of 3 N on a 0.25 kg magnet. What force will the smaller magnet exert on the larger magnet?
wondering if the magnets are allowed to move (accelerate)?
assuming not, then each is pulling with 3N.
To find the force exerted by the smaller magnet on the larger magnet, we can use Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Given:
Mass of the larger magnet (m1) = 5 kg
Mass of the smaller magnet (m2) = 0.25 kg
Force exerted by the larger magnet on the smaller magnet (F1) = 3 N
According to Newton's third law, the force exerted by the smaller magnet on the larger magnet (F2) will be equal in magnitude but opposite in direction to F1.
Therefore, F2 = -F1
F2 = -3 N
So, the force exerted by the smaller magnet on the larger magnet is 3 N in the opposite direction.
