Question

7. A wooden block floats in the water such that its ¾ th part remains below the water.
What is the relative density of the block.

Answer 1

Answer:

Let X be the density of wood.

Density of water

Density of wood

= Part of block submerged

So,

1000

X

=

3

2

or, X=

3

2

×1000=666.66kgm

−3

Answer 2

let X with the density of wood density of wood by density of water is equal to part of submerged so text by 1000 is equal to 23 or x is equal to 2 by 3 X 2016 6.66 kg - 3
