an iron box immersed in water,kerosene and coconut oil separately.does same force of buoyant force on iron box in all liquids?
No, the buoyant force experienced by an object submerged in a fluid depends on the density of the fluid and the density of the object. The buoyant force is the upward force exerted on an object submerged in a fluid, and it is equal to the weight of the fluid displaced by the object.
In this case, water, kerosene, and coconut oil are three different liquids, each with their own densities. Therefore, the buoyant force on the iron box will vary depending on the density of the liquid.
To determine if the buoyant force is the same in each liquid, you would need to compare the densities of water, kerosene, and coconut oil and compare them to the density of the iron box. The density of an object is typically measured in kilograms per cubic meter (kg/m³), while the density of a fluid can also be measured in similar units.
You can find the density of water, kerosene, and coconut oil online or refer to scientific references. Once you have the densities, compare them to the density of the iron box. If the density of the fluid is greater than the density of the iron box, then the buoyant force will be less. Conversely, if the density of the fluid is less than the density of the iron box, then the buoyant force will be greater.
Remember, the buoyant force will always act in the upward direction, opposing the force of gravity on the submerged object.
