Dear Student!!
Effective weight of the solid is more in air then the liquid.
Archimedes principle states that when a body is immersed wholly or partially in a liquid, it experiences an upward buoyant force of magnitude equal to the weight of the liquid displaced by it.
Buoyant force = Weight of displaced liquid
Weight of displaced liquid = Mass of the displaced liquid × Acceleration due to gravity
= Density of the liquid × Volume of the displaced liquid × Acceleration due to gravity
∴Volume of the displaced liquid = Volume of the object that is immersed in the liquid
∴Weight of the displaced liquid = Volume of the object immersed in the liquid × Density of the liquid × Acceleration due to gravity
Hence, we can write the magnitude of the upthrust on an object that is immersed in a liquid as Buoyant force = Volume of the object × Density of the liquid × Acceleration due to gravity
Since buoyant force depends on the density of the liquid in which it is immersed, it is different in different liquids for the same object
