Question

When a body is placed in a liquid it remaining in the same position. Why?

Answer 1

Answer:

all the objects placed in a liquid experience an upward force which allows the body to float if it displaces water with the weight equal to the weight of the body. This upward force is known as buoyant force and the law is known as the law of buoyancy.

Answer 2

• Any object in a fluid experiences an upward force that causes the body to float when it pushes the water with a weight equal to that of the body.
• This upward force is called the buyount force, and this law is called the law of the buoyant force.
• The principle of Archimedes states that the buoyant force acting on an object immersed in a completely or partially immersed liquid is equal to the weight of the displaced liquid.
• [1] Archimedes' principle is the basic law of physics in fluid mechanics. It was formulated by Archimedes of Syracuse.

• A liquid or an object completely or partially immersed in a liquid is lifted with a force equal to the weight of the liquid displaced by this object.

• A floating object's weight Fp and its buoyancy Fa (Fb in the text) must be equal in size.
• The principle of Archimedes allows you to calculate the buoyancy of any floating body, partially or completely immersed in a liquid.
• The downward force on an object is simply its weight. The lift or buoyancy force on an object is determined by the above principle of Archimedes.
• Therefore, the net force acting on an object is the difference between the magnitude of the buoyant force and its weight. If the resulting force is positive, the object will float. If negative, the object sinks.
• If 0, the object is neutral.
• That is, it stays in place, neither rising nor falling.
• Simply put, Archimedes' principle states that when an object is partially or completely immersed in a fluid, it experiences a weight loss equal to the weight of the fluid displaced by the submerged body part.
