Question

a) A block of mass 150 kg has a volume of 3m3

. Calculate its density in (a) kg m-3

(b) g cm-3​

Answer 1

Answer:

Here, mass m=100kg,

density ρ=500kgm

−3

Volume of the body, V=

ρ

m

=

500

100

=0.2m

Weight of water displaced

=Vρg

=0.2×10

×g

=200gkgwt

Mass of water displaced =200kg

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

=200−100=100kg
