Archimedes, Buoyancy, & Density

A floating object displaces a fluid having a weight equal to the weight of the object as per the

• principle of floatation

• Einstein principle

• Pascal's principle

• Newton's principle

If the weight of an object is equal or less than the up thrust acting on it then the object would

• balance

• equal

• float

• sink

If the weight of an object is greater than the up thrust acting on it then the object would

• balance

• equal

• float

• sink

The object will sink if its weight is

• greater than up thrust on it

• less than up thrust acting on it

• equal to up thrust acting on it

• all of above

The upward force exerted by a liquid on an object immersed in or floating on the liquid

• pressure
• buoyant force
• normal force
• gravity

The upward force exerted by a liquid on an object immersed in or floating on the liquid
