Question

ii. A body weighs 20 gf in air and 18.0 gf in water. Calculate the relative density of the material of

the body.​

Answer 1

Answer:

Given,

Weight of the body in air = 20gf ( Wa)

Weight of the body in water = 18gf ( Ws)

Weight of the body in liquid =18.2gf ( Wl)

Now,

The loss of weight in the water = 20 - 18 or, 2 gf

So the relative density of the body is = Wa / ( wa - ws )

= 20 / 2

= 10
