Question

A wooden raft of denity 600kg/m^3 and mass 120kg floats on water. How much weight in kg can be put on it to make its volume ink and top urface coincide with the water surface.

and pleae give the statements and explanation also.....

Answer 1

$\bf\red{SOLUTION}$


Assuming density of water to be 1000 kg/m3

We have,

Total mass of object+mass of body 2=weight displaced in water

Total mass of object= 120kg=120X9.81N

Mass of body 2= let it be m

Weight displaced in water=1000X(volume of object) X9. 81

Volume of object= mass/density=120/600=0.2 m3

Hence ,

m+1177.2=1962

Or m=784.8N=784.8/9.81=80kg.......

Answer 2

may it will help you.
