Question

A body of mass 100kg and density 500kgm-3 is floating on water. For the body to sink,the minimum additional mass to be added to the body is​

Answer 1

Explanation:

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
