Question 35

A tall glass column in a laboratory contains two stationary liquid layers that do not mix. The upper layer is liquid A, with a height of 0.35 m and a density of 900 kg/m3. The lower layer is liquid B, with a height of 0.25 m and a density of 1100 kg/m3. Take g=10 N/kgg=10\ \mathrm{N/kg}g=10 N/kg.

Which liquid layer causes the greater increase in pressure from its own weight?

[1]
A

Both layers cause the same increase in pressure

B

The information is insufficient to compare the pressure increases

C

Liquid A

D

Liquid B
