Question
Ram throws a stone in the pond. It displaced 1.5 kg of water. Calculate the buoyant force acting on the stone. (g = 9.8 m/s²)
Solution
To calculate the buoyant force, we can use Archimedes' principle which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
Step 1: Identify the mass of the water displaced by the stone. In this case, it is given as 1.5 kg.
Step 2: Identify the acceleration due to gravity. In this case, it is given as 9.8 m/s².
Step 3: Use the formula for weight (which is a force), which is mass times gravity.
So, the buoyant force (F) = mass of water displaced (m) x gravity (g)
F = m * g F = 1.5 kg * 9.8 m/s² F = 14.7 N
So, the buoyant force acting on the stone is 14.7 Newtons.
