Correct Answer: Option A
Explanation:
R.d = \(\frac{0.4}{0.5}\) = 0.8
0.8 = \(\frac{\text {Density of oil}}{\text{Density of water}}\)
0.8 = \(\frac{\text {Density of oil}}{1000}\)
Density of oil = 800kgm3
R.d = \(\frac{0.4}{0.5}\) = 0.8
0.8 = \(\frac{\text {Density of oil}}{\text{Density of water}}\)
0.8 = \(\frac{\text {Density of oil}}{1000}\)
Density of oil = 800kgm3
