Give reasons -
There is a block of ice of volume V . Can it be kept inside a hollow sphere of volume V? If the ice melts , now can it be kept inside the same sphere?
Pls answer it , with reason.

Answer:
Given the body is half immersed in the water. Let ρ be the density of water and m be the mass of the sphere initially.
⇒mg=
2
V
ρg
Let V
0
volume is added to the sphere. Then the weight of sphere =mg+V
0
ρg
After it is completely immersed:
Buoyancy force =Vρg
Both the forces should be equal:
⇒mg+V
o
ρg=Vρg
⇒V
0
=
2
V
