Question
A 10 kg ball weighs 98 N in air and weighs 75 N when submerged in water. The upward buoyant force on the ball is
Solution
The upward buoyant force on the ball can be calculated using Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
In this case, the weight of the ball in air is 98 N and the weight of the ball when submerged in water is 75 N. The difference between these two weights is the buoyant force.
So, the buoyant force = weight in air - weight in water = 98 N - 75 N = 23 N
Therefore, the upward buoyant force on the ball is 23 N.
