Question

Write about buoyant force.

Answer 1

1. An upward force is exerted by water on a floating or a partially submerged body. This upward force is called buoyant force. The phenomenon is known as “buoyancy”.
2. This force is not only exerted by liquids, but also by gases. Liquids and gases together are called fluids.
3. This upward force decides whether an object will sink or float. If the weight of the object is less than the upward force, then the object will float. If not, it will sink.
