A solid plastic toy is fully submerged in a tub of water on Earth and then in an identical tub of water on the Moon, where the gravitational acceleration is approximately one-sixth of Earth’s. Which statement correctly describes how the buoyant force acting on the toy changes?
(a) The buoyant force on the Moon is the same as on Earth because the density of water does not change.
(b) The buoyant force on the Moon is one-sixth of that on Earth because the weight of the displaced water is reduced in the same proportion.
(c) The buoyant force on the Moon is greater than on Earth because the toy weighs less, allowing the water to push upward more strongly.
(d) The buoyant force on the Moon is one-thirty-sixth of that on Earth because both the density of the water and the gravitational acceleration are lower.
