Question

the pressure P¹ is at a curtain depth in river water and P² at the same depth in sea water. state the relationship between P¹ and P ²​

Answer 1

Answer:

The density of the sea water is greater than the density of the river water.

The pressure of river water is p1 and density is d1

while pressure of sea water is p2 and density is d2

We know,

p1 = h1 d1 g ...(1)

p2 = h2 d2 g ...(2)

Given: h1 = h2

Thus, dividing equation (1) by (2), we have,

p1/p2 = d1/d2

As, d2>d1,

p2>p1

Thus, the relation between the pressure at same depth of river water and sea water is given as,

p2>p1.
