Question

A wooden block of 200 kg floats on water. What is the upthrust force act on the block? (g = 10ms-2)​

Answer 1

Answer:

volume of the wooden block and water displaced will same

water will have more density than block (that's why it's floating)

so

mass of block =

$100kg \:$

volume of block = V = volume of water displaced

density of water d1 > density of block d

100 = V × d

V = 100/d

upthrust = V × d1 × g

=

$1000d1/d \: \: \: \:$
