Question

a ball is floats on water with its own fifth volume outside water. What is density of rubber.​

Answer 1

Answer:

Part outside water = 1/5

Part immersed = 1-1/5 = 4/5

According to the Floatation principle,

v/V = density of substance/Density of liquid

= 4/5 = x/1

= 0.8 g/cc = x = Density of substance or rubber.

Hope this helps.
