Question

100 cm weighs 1,kg in air. Find :
A body of volume 10
(i) its weight in water and (ii) its relative density.​

Answer 1

Answer:

Given:

Volume of the body =100 cm

3

Weight of the body in air, W

1

=1 kgf or 1000 gf

Let weight of the body in water be W

2

We know that R.D. of water is 1 and that of a solid is 10

To find the weight of the body in water

Relative density of the body =

W

1

−W

2

W

1

× relative density of water

10=

1000−W

2

1000

×1

10(1000−W

2

)=1000

W

2

=1000−100=900 gf

Answer 2

Answer:

it's weight in water and
