SUMMARY
The discussion centers on calculating the force required to keep a ball submerged in water, given its density of 900 kg/m³ and a volume of 0.03 m³. The net force acting on the ball can be determined using the equation F_net = ma, where 'm' is the mass of the ball and 'a' is the acceleration due to gravity. The buoyant force acting on the ball must be countered by an external force to maintain equilibrium underwater. The specific calculations involve determining the weight of the ball and the buoyant force exerted by the displaced water.
