Question

Observe the vessels A, B, C and D as shown in figure carefully.

300 mL	50 mL	500 mL	60 mL
A	B	C	D

Answer 1

Pressure at depth due to the liquid column depends upon

1. Gravitational acceleration (g)
2. Density of liquid
3. Height of liquid

And in this case, g and density are same, so only thing that can change pressure is height.

So, the order of pressure exerted by the fluid A, B, C and D at the base is given by

PD > PB > PA > PC
