Question

Why does an object float or sink when placed on the surface of water?

Answer 1

Buoyant Force:

1. The net upward force on any item in any fluid is known as buoyant force. The object will rise to the surface and float if the buoyant force is higher than its weight. The object will sink if the buoyant force is less than its weight.
2. Buoyancy is a force acting on an item that causes it to rise or move higher. The difference in the pressure exerted on the item by the fluid or air in which it is submerged creates buoyancy.
3. The buoyant force causes the thing to float or sink. When an item is submerged in a liquid, it experiences a buoyant force, which causes it to rise. The upward-pulling buoyant force.
4. Now, whether an object will float or sink in water is determined by the magnitudes of these two opposing forces acting on the object.
