Where F b is the buoyant force, ρ is the density of the fluid, V is the submerged volume, and g is the acceleration due to gravity Archimedes Principle Formula: In simple form, the Archimedes law states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.If only a part of the volume is submerged, the object can only displace that much liquid. If the object has a volume of V, then it displaces a volume V of the liquid when it is fully submerged. Archimedes' principle tells us that this loss of weight is equal to the weight of liquid the object displaces.When an object is partially or fully immersed in a liquid displaced by it. The value of thrust force is given by the Archimedes law which was discovered by Archimedes of Syracuse of Greece.Archimedes Principle: The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the centre of mass of the displaced fluid.It says that "a pressure exerted anywhere in a point of the confined fluid is transmitted equally in all directions throughout the fluid”.Pascal’s principle: Pascal’s Law is the principle of transmission of fluid-pressure.Bernoulli's principle: For a streamlined flow of an ideal liquid in a varying cross-section tube the total energy per unit volume remains constant throughout the fluid.Thus a balloon is based on the Archimedes principle.Due to the difference in density, the balloon lifted above the ground and moves up in the air.When the air is being heated the density of that air gets reduced compared to the density of surrounding air or we can use the gas having less density than that of air.The balloon is based on the principle of Archimedes.Archimedes principle: Any object which is floating in a fluid is acted upon by an upward force whose magnitude is equal to the weight of the fluid displaced.A simple device that uses hot air or light gas to move up in the air is called a balloon.
So the actual mass/True mass (x) = 100 gm. Where ρ o is the density of the object, V o is the volume of the object, g is the gravitational acceleration. Here weight of object ( W) = mg = ρ o V o g When an object is submerged in fluid fully or partially there are two forces, 1.Where ρ f is the density of the fluid in which the object is submerged, V f is the volume of the displaced fluid (or volume of the object that is submerged inside the fluid) and g is the gravitational acceleration. Archimedes' principle states that when a body immersed in a fluid, whether fully or partially submerged, the upward buoyant force that is exerted on it, is equal to the weight of the fluid that the body displaces.
