A 10.0 kg ball weighs 98.0 N in air and weighs 65.0 N when submerged in water. The volume of the ball is

Question

Quizplus · Accepted Answer

The correct answer is A because the buoyant force is equal to the weight of the water displaced by the ball. The weight of the water displaced is equal to the density of water times the volume of the ball times the acceleration due to gravity. The density of water is 1000 kg/m^3 and the acceleration due to gravity is 9.8 m/s^2. So, the volume of the ball is:V = (98.0 N - 65.0 N) / (1000 kg/m^3 * 9.8 m/s^2) = 0.00337 m^3
