Question 1 Report

If a plastic sphere floats in water (density = 1000kgm3) with 0.5 of its volume submerged, and floats in oil with 0.4 of its volume submerged the density of the oil is

800kgm3

1200kgm3

1250kgm3

2000kgm3

Answer Details

R.d =

\frac{0.4}{0.5}

= 0.8

0.8 = $\frac{Density of oil}{Density of water}$

0.8 = $\frac{Density of oil}{1000}$

Density of oil = 800kgm3
