A beaker is filled with water to its brim. A ball of mass 1 kg is slowly dropped into it. If water weighing 5 N falls out of the beaker, the buoyant force experienced by the ball is
4 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 5 N, so the buoyant force would be 5 N.
