A beaker is filled with water to its brim and a ball of mass 100 kg into it. The amount of water displaced is 10 kg. Find the buoyant force experienced by the ball.
3 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 10×10=100N, so the buoyant force would be 100 N.
