A solid 0f density D has weight W it's completely immense on liquid of density d then apparent weight of solid is
Completely immersed ON. Do you mean on or in? If completely immersed it must be IN.
To find the apparent weight of a solid immersed in a liquid, you can use the concept of buoyancy. The apparent weight, also known as the buoyant force, can be calculated using the following formula:
Apparent weight = Weight of solid - Buoyant force
The weight of the solid is represented by W, and the buoyant force can be found using Archimedes' principle, which states that the buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
The weight of the fluid displaced is given by:
Weight of fluid displaced = Volume of solid × Density of liquid × Acceleration due to gravity
The volume of the solid can be calculated using its density (D) and its weight (W):
Volume of solid = Weight of solid / Density of solid
Combining these equations, we can calculate the apparent weight of the solid:
Apparent weight = W - (Volume of solid × Density of liquid × Acceleration due to gravity)
Therefore, the apparent weight of the solid immersed in the liquid can be obtained using the formula mentioned above.
