Question

the volume of the metallic Bob of mass 700 gram is 350 cm (i) find density of buoyant Bob (ii)when in water what weight of water displaced

Answer 1

HEY MATE HERE IS YOUR ANSWER

Given,

volume of metallic Bob =350cm

Mass=700g

(i)We know,

Density=mass/volume

So,density =700/350

2g/cm.

so, the density of the buoyant bob=2g/cm.

(ii)According to the Archimedes law

weight of the displaced is the same as the weight of the bob.

So,

The weight of the displaced water=
mg [g = 9.8m/s^2 and m is the mass]

So, the weight of the displaced water =
7×9.8 [as 700g=7kg]

=6.86 Newton.
