Water weighs about 10 N per liter. A 4.0 kg ball floats on the water's surface. What is the weight of the water being displaced by the ball?

Question

Quizplus · Accepted Answer

The weight of the water displaced by the ball is equal to the weight of the ball itself due to the principle of buoyancy. Since the ball weighs 4.0 kg and the acceleration due to gravity is approximately 9.8 m/s^2, its weight is 4.0 kg * 9.8 m/s^2 = 39.2 N, which is about 40 N.
