Weight = mass × acceleration due to gravity
Weight (in water) = mass × 9.8 m/s²
However, the apparent weight of the block in water will be less than its actual weight due to the buoyant force acting upwards. This buoyant force is equal to the weight of the water displaced by the block.
Therefore, the force of gravity acting on the block in water is the same as its weight in air, but the net force acting on the block is reduced by the buoyant force.
Here's a more detailed explanation:
* Weight (in air): This is the force of gravity acting on the block due to its mass. It remains constant regardless of the surrounding medium.
* Buoyant force: This is an upward force exerted by the fluid (water) on the block. It is equal to the weight of the fluid displaced by the block.
* Apparent weight (in water): This is the net force acting on the block, which is the difference between its weight and the buoyant force. It is less than the block's actual weight because the buoyant force partially counteracts gravity.
To calculate the apparent weight of the block in water, you would need to know the volume of the block and the density of water to determine the buoyant force.
