Question

A block of wood is floating in water. The portion of block inside the water measures
50cm ×50cm×50cm. What is the magnitude of the buoyant force acting on the wooden
block in SI unit? [g = 10 msec-2
]

Answer 1

Answer:

Density of water, ρ=1000 kg m

−3

According to Archimedes principle, the buoyant force acting on an object is equal to the weight of the liquid displaced.

Volume of water displaced = 50×50×50×10

−6

m

3

=0.125 m

3

Weight of water displaced = 0.125×1000×9.8=1225 N

X=1225
