Answer 1

Answer:

29.12 gf

Explanation:

Weight of the solid in air,

W1 = 32 gf

Weight of the solid in water,

W2=28.8 gf

Density of the liquid =0.9 gcm

To find the weight of the solid in a liquid

Let W3 be the weight of the solid in liquid.

We know that, R.D. of solid

$= \frac{w1}{w1 - w3} \times relative \: density \: of \: liquid$

$= > 10 = \frac{32}{32 - w3} \times 0.9$

=> w3 = 29.12 gf (Ans)
