 hollow sphere of negligible mass and radius R is completely filled with a liquid so that its density is ρ. You now enlarge the sphere so its radius is 2R and completely fill it with the same liquid. What is the density of the enlarged sphere?


1- 4 ρ 
2- ρ/2 
3- ρ/8

Density = Mass/Volume

as mass remain same

As Radius become 2 times ,volumme beomes ^3 = 8times

So

Density = p/8
