Question

A bag of 1 Kg is hanging on one end of a stick. If we hold the stick near the bag, we can easily hold it. We will have to apply more force if we hold the stick far from the bag. If the force of gravity on bag is same, and we are increasingly applying more force, how are the forces still balanced? Note that if the forces weren't balanced, the bag would start to move (Newton's first law). ​

Answer 1

Answer:

This happens because of the law of gravitational forces. Let's consider the first end of stick, to which the hand is holding as origin. When the bag is near to origin, the weight is felt originally (which is a real weight of bag=1kg) but as we move the bag away from origin, the factor of distance starts getting added to the weight factor, this is due to the law of gravitational forces, hence the bag feels heavy as it moves away from origin and bag becomes heavier; and the point arise where it becomes impossible to hold the bag due to increased weight and we have to let go of it.
