Question

(a) Define buoyant force. Name two factors on which buoyant force depends.
(b) What is the cause of buoyant force?
(c) When a boat is partially immersed in water, it displaces 600 kg of water. How much is the buoyant force acting on the boat in newtons? (g = 10 m s−2)

Answer 1

Answer:

The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth.

Answer 2

When a object is fully o4 partially immersed in a liquid, the liquid exert a

force on the object in the upward direction it is called buoyancy......

• weight of the object
• density of liquid
