Question

When Both liquids and _____ exert a buoyant force?

Answer 1

Gases is the word which had to be filled.

When both liquids and gases exert a bouyant force?

The upward force that is exerted by a liquid on a body which is submerged in it is known as a buoyant force. Its also known as upthrust. Not only liquids but also gases exert upthrust.

Answer 2

ANSWER

Buoyant Force

1)Any object experiences buoyant when it is merged or submerged in a liquid such as water.

2)Greater the depth greater the buoyant force exerted on an object by the liquid and also the pressure in the body increases as well.

The buoyant force exerted by the fluid on the body is directly proportional to the depth.

3)An object which has an average density more than that of liquid in which it is submerged tend to sink.

And an object which has an average density less than that of liquid in which it is submerged tend to float.

4)Both liquids, as well as gas, exerts this property.

Extra Information

Archimedes Principle states that if anybody wholly or partially emerges in a fluid is buoyant up by a force equal to the fluid displaced by the body.

°°buoyancy= weight of displaced fluid.

°°density = $\dfrac{mass}{volume}$

°°This principle is so useful that it has many applications in nowadays.

example=>In submarines,balloons etc.
