Question

Find the density of wooden block if wooden block convert in a cylinderical rod where,
mass of wooden block - 500g
mass of rod - 100g
if we dive rod into water. water increases and comes to 50ml upper.
density of water - 300 x 10^-5​

Answer 1

Explanation:

Correct option is

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
