Question

The upward force experienced by a body when partly or wholly immersed in a fluid is ________.

Answer 1

1. When a body is wholly or partly immersed in a fluid, it becomes apparently lighter due to an upward force acting on it.
2. The upward force acts opposite to the direction of the weight of the body.
3. The upward force acting on the body is called buoyant force.
4. The buoyant force is directly proportional to the density of the fluid in which a body is immersed.

Hence, the upward force experienced by a body when partly or wholly immersed in a fluid is called buoyant force.
