Question
A) If F, V, d and g represents buoyant force, volume of liquid displaced, density of the liquid and acceleration due to gravity, write an expression to find F and d. [2]
Solution
The buoyant force (F) is given by Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. The weight of the fluid is its mass times the acceleration due to gravity (g). The mass of the fluid is its volume (V) times its density (d). Therefore, the buoyant force is given by the equation:
F = d * V * g
To find the density (d), you can rearrange this equation to solve for d:
d = F / (V * g)
