Question

the Density of the material of a given object is 2800kg/m3 . Find the volume of this Object in cm3 if it's mass is 1.4kg​

Answer 1

Explanation:

B

100 kg

Here, mass m=100kg,

density ρ=500kgm

−3

Volume of the body, V=

ρ

m

=

500

100

=0.2m

3

Weight of water displaced

=Vρg

=0.2×10

3

×g

=200gkgwt

Mass of water displaced =200kg

∴ the additional mass which can be added to body, so that body can sink

=200−100=100kg
