Marks: +1, -0

The ratio of pressures between two points A and B located respectively at depths 0.5 m and 2 m below a constant level of water in a tank is

Solution:

Pressure under water column (level is constant) is expressed by → P = ρ.g.H;
Thus,

P_1 / P_2 = H_1 / H_2

So,

P_1 : P_2 = 0.5 / 2 = 1 / 4 \or 1:4
