Concept:
Archimedes Principle: When a body is fully or partially dipped in fluid, the fluid exerts a contact force on the body. The resultant of this contact force is known as buoyancy or buoyant force.
- This force acts vertically upwards (opposite to the weight of the body).
- Mathematically, F = Vρg [where, V = volume of liquid displaced, ρ = density of the liquid, g = acceleration due to gravity.]
- A body floats on a fluid if the average density of the body is less than that of fluid.
- The weight of the liquid displaced by the immersed part of the body must be equal to the weight of the body.
Calculation:
Given:
m = 700 g = 0.7 kg, a = 10 cm
In floating bodies,
Weight of fluid = Buoyant force
Buoyant force = weight of water displaced. If V is the volume of cube inside the water, then the weight of water displaced = Vρg.
⇒ Vρg = 0.7 g
Total volume of the cube = (10 cm) 3 = 1000 cm3
∴ Volume outside the water = 1000 – 700 = 300 cm3
