Question

A body of mass 70kg when completely immersed in water displaces 20000 cm^3 of water. find the weight of the body in water and the relative density PS material is body. ​

Answer 1

Given:

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
