What is cause of buoyant force?
Answers
Answer:
Buoyant force is the upward force exerted by fluid on an object submerged on it.
Explanation:
Buoyant force is nothing but the upward force exerted by fluid on an object submerged on it. This is due to the difference in pressure between the top of the submerged object and the bottom. The more deeper the object sinks,the more will be the pressure acting at the bottom of the object.This can be realised by the equation, Pressure=Height from the surface of the fluid×Density of the fluid×Acceleration due to gravity.Hence,the force experienced by the object,which we call the buoyant force, will be greater.
pressure exerted by a liquid increase with depth and act in all direction. So, the upward force exerted by the liquid on the bottom of an object is greater than the downward force acting on the top of the object. This gives rise to net force acting on the object in the upward direction, which accounts for the buoyant force.
