Answer:
Given:
Weight of the solid in air =120 gf
Weight of the solid when completely immersed in water =105 gf
Relative density of a solid =
weight of the solid in air−weight of the solid in water
weight of solid in air
×R.D. of water
=
120−105
120
×1=8Given:
mass of the body =70 kg
Volume of water displaced =20,000 cm
3
or 0.02 m
3
Density in C.G.S = mass/ volume =70×1000/20000=3.5 g cm
3
Relative density of the solid = density in C.G.S. without unit
=3.5
