🔍 Key Concepts

• Archimedes' principle and what it says about buoyant force • Difference between pressure in a fluid and the resultant force on an immersed body • Meaning of center of gravity of displaced fluid (center of buoyancy)

💭 Think About

• When an object is submerged, what overall force does the fluid exert on it, and in which direction does that net force act? • How is the magnitude of this net force related to the volume (or weight) of fluid displaced by the object? • Which option is talking about pressure everywhere in the fluid, and which option is talking about a single net force on the body?

✅ Before You Answer

• Identify which choice clearly describes a single resultant force rather than general pressure behavior in a fluid • Check which option connects the effect on the body to the weight of the displaced fluid • Eliminate any choice that talks about forces or pressures that do not act through the displaced fluid’s center or that are equal in all directions (that’s general fluid pressure, not Archimedes’ principle)
