Question:
A platinum sphere with radius 1.21 cm is totally immersed in mercury. Find the weight of the sphere, the buoyant force acting on the sphere, and the sphere's apparent weight. The densities of platinum and mercury are 2.14 x 104 kg/m3 and 1.36 x 104 kg/m3, respectively.
Apparent Weight:
Apparent weight is the difference between the object's real weight and the buoyant force acting on it. The buoyant force is the upward force on an object when it is submerged in a fluid. It depends on the density of the fluid and volume of the object in the fluid.
