Question

A 2kg block of wood is floating in water. What is the magnitude ofthe buoyant force acting on the block?

A)Zero
B)2kg
C)19.6N
D)2000N
E)It cannot be determined since we do not knowthe density of the wood. Hint: If it is floating it is not accelerating, the net force mustbe zero. So the magnitude of the buoyant force must be equalthe weight. B = mg.

Explanation / Answer

Given : .             Mass of th block (m) = 2 kg . As the block of wood is floating in water , . The Magnitude of buoyant force acting on the block is : .            F   =   mg   = 2 kg  * 9.8 m /s2   = 19.6 N . Hope this helps u!
