Question

7 A solid weighs 0.850 kgf in air and 0.575 kgf when completely immersed
in
water. Find i) relative density of the solid ii) upthrust on the solid using
Archimedes' principle. [write the formulae used]
(2)​

Answer 1

Answer:

Weight of solid in air = 0.08 kgf

Weight of solid in water = 0.065 kgf

Density of water = 1000 kgm3

(1) Relative density (RD) of solid

= Weight of solid in air

wt. of solid in air-wt. of solid in water
