The magnitude of the force exerted by the rope on the bucket is 8N.
To find the answer, we need to know about the force.
<h3>What's force?</h3>
- According to Newton's second law, force is expressed as rate of change of momentum.
- It can be written as mass × acceleration.
<h3>What's the force experienced by an object, when it moves with constant velocity?</h3>
- When an object moves with constant velocity, its acceleration is zero.
- Since acceleration is zero, so the force experienced by it is zero.
Thus, we can conclude that there's no force on the bucket by the person as he is lowering it by constant velocity. But force on the bucket by the rope is 8N.
