Question

Where is pressure greater ,10 m below the surface of a sea or 20 m below?

Answer 1

20 m below the sea level.

P=hdg

Where P=pressure

h=depth or height below the surface of water

d=density of water

g=acceleration due to gravity.

From the above equation it is well understood that pressure is directly proportional to height or depth, so it increases with increase in depth.
