Question

Find the density when a liquid 5m in a column exerts a pressure 80Pa
(A) 625 kg/m
(B) 1.6 kg/m3
(C) 0.625 kg/m
(D) 2.625 kg/m3
3​

Answer 1

Answer:

B

Explanation:

Pressure at a depth = Density of Substance x Depth x Acceleration due to gravity

80 Pa = Density of Substance x 5 m x 9.8 $\frac{m}{s^{2} }$

Density of Substance = 80/(5x9.8) = 1.63 $\frac{kg}{m^{3} }$

So answer is B
