Final answer:
The buoyant force on ice held completely submerged under water can be calculated using the formula: Fbuoyant = density of water × volume of object × acceleration due to gravity.
Step-by-step explanation:
The buoyant force on an object submerged in water is equal to the weight of the water displaced by the object. Since the ice is completely submerged in water, the buoyant force on it is equal to the weight of the water it displaces.
The volume of the ice is its mass divided by its density. Using the density of ice and the given mass, we can calculate the volume of the ice.
The buoyant force on the ice can then be calculated by multiplying the volume of the ice by the density of water and acceleration due to gravity.
The formula for calculating the buoyant force is:
Fbuoyant = density of water × volume of object × acceleration due to gravity
