Question

A metal block of density 900kgm^-3 weighs 60N in air, find its weight when it is immersed in paraffin wax of density 800kgm^-3

​

Answer 1

Given;

Density of metal block : 900 kg/m3

Weight in air of block : 60N

Weight of block when it is immerse in

paraffin wax = ?

Mass of block = 6kg

NOW,

Volume = 6 kg / 900 kg/m3

= 0.0067 m3

And

Mass = 800 × 0.0067

= 5.333

And

Weight = 5.33 × 10

=53.33
