A beaker is filled with water to its brim. A child while playing drops his ball of mass 1 kg into it and eventually ends up with wetting himself with water. He weighs the water fallen on him and found it to be 1 N. Find the buoyant force experienced by the ball. (Assume that the ball drops slowly)
1 N
According to Archimedes principle, the weight of the liquid displaced is equal to the buoyant force. Here the weight of the displaced liquid is 1 N, so the buoyant force would be 1 N.
