A sphere of metal weighs 287.7 N in air. When placed in water, its weight is 71.8 N. What is the buoyant force? Using significant figures report your answer to 1 decimal place.

Answer 1

Conceptual Understanding:

Buoyant force is the difference between the weight of the object in water to the weight of the object in the air. Buoyant force is the force upwards on an object that is exerted by the surrounding fluid.Think of an object that rises, sinks, or remains suspended in the fluid.

F_b = 287.7 N - 71.8 N = 215.9 N
