Ice.
Because the hollow ball is larger than the solid one. It displaces enough of the fluid to equal its weight, so it floats.
Ice floats on water because it is less dense than liquid water. When water freezes, it forms a crystalline structure that spaces the water molecules farther apart, making the ice less dense and causing it to float.
The question first states that the two objects " ... have the same mass", and then asks "Which one has the greater mass?"This does not compute.Just from the fact that one floats and the other sinks, we can't conclude anything regarding their relative masses, without knowing their respective shapes.Consider all the steel in a battleship being rolled up into a solid ball ...

Energy itself cannot float in water as it is not a physical substance that can be contained in a way that would allow it to float. However, forms of energy such as heat or mechanical energy can be transferred to water and affect its properties.
Suspensions are mixtures in which the density of the liquid and the solid are such that the solid neither sinks not floats in the liquid but is suspended throughout.
A solid that has a density greater than the density of the medium it is placed in (i.e. water). So a piece of lead is more dense than water, and so it sinks. Styrofoam is not very dense, and it floats.
Put it in water. If it floats, it's less dense. If it sinks, it's more dense.
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.
The solid state of water is less dense than its liquid state, which is why ice floats on water. The solid state of nearly all other substances is more dense than the liquid state and sinks in the liquid state.

Ultraoversimplifying it, the coin is solid metal all the way through and weighs more than its volume of water, the ship has a large space filled with air inside it resulting in the weight of the ship and cargo being less than the weight of the volume of water it occupies.This is called buoyancy: the coin has negative buoyancy and sinks, the ship has positive buoyancy and floats.
