Given Data:
- Weight of wooden block in air: 10 N
- Weight of wooden block in water: 6 N
Calculating the Buoyant Force:
- When the block is in water, it displaces water equal to its own volume.
- The weight of the water displaced by the block is equal to the buoyant force acting on the block.
- Buoyant force = Weight of block in air - Weight of block in water
- Buoyant force = 10 N - 6 N
- Buoyant force = 4 N
Therefore, the buoyant force acting on the block is 4 N, which is option B.
- Weight of wooden block in air: 10 N
- Weight of wooden block in water: 6 N
Calculating the Buoyant Force:
- When the block is in water, it displaces water equal to its own volume.
- The weight of the water displaced by the block is equal to the buoyant force acting on the block.
- Buoyant force = Weight of block in air - Weight of block in water
- Buoyant force = 10 N - 6 N
- Buoyant force = 4 N
Therefore, the buoyant force acting on the block is 4 N, which is option B.

- b)The buoyant force decreases.
- c)The buoyant force remains the same.
- d)The buoyant force is zero.

Capstone Ias Learning answered |
The buoyant force experienced by an object in a fluid depends on the weight of the displaced fluid, which is determined by the volume of the object submerged. If the object is partially submerged, the volume of the displaced fluid and thus the buoyant force remain the same.

- b)Density of the fluid.
- c)Weight of the object.
- d)Surface area of the object.

Spectrum Coaching Institute answered |
The buoyant force depends on the volume of the object submerged, density of the fluid, and weight of the object. The surface area of the object does not directly affect the buoyant force.

The principle of floatation is not directly related to the conservation of mass, energy, or momentum. It is based on the law of conservation of volume, which states that the volume of fluid displaced by an object is equal to the volume of the object.

For a floating object to be stable, its center of gravity should be below its center of buoyancy. This ensures that any small tilting or displacement will create a restoring torque, causing the object to return to its equilibrium position.

If two-thirds of the wood's volume is submerged in water, it means that the wood is less dense than water. The density of the wood is greater than the density of water because it sinks but only partially.

According to Pascal's law, the pressure in a fluid at rest is transmitted equally in all directions. This is why, for example, when you squeeze a closed container filled with fluid, the pressure is distributed uniformly throughout the fluid.

Similar to a floating object, the stability of a submerged object is increased when its center of gravity is below its center of buoyancy. This ensures that any tilting or disturbance will create a restoring torque, bringing the object back to equilibrium.

According to Archimedes' principle, an object floats when the buoyant force acting on it is equal to or greater than its weight. In the case of a ship, the weight of the ship is less than the buoyant force exerted by the water, allowing it to float.

Pascal's law states that pressure applied to a fluid is transmitted undiminished in all directions. A hydraulic lift utilizes this principle to generate a large force by applying a small force to a confined fluid, which is then transmitted to lift a heavier load.
