Question

Quizplus · Accepted Answer

The buoyant force on the boat is determined by the weight of the water displaced by the boat, not by the water's density. Since the boat displaces the same volume of water in both cases, the buoyant force remains the same in both fresh water and salt water.

Salt Water Has Greater Density Than Fresh Water
