We study water of 1.0 g/cm3 density in an open container with its surface exposed to the atmosphere. If we measure the pressure first at a depth d and find the value p1, and then at twice that depth to find p2, the two results are related in this form:

Question

a) p1> p2
b) p1=p2
c) 2 p1> p2
d) 2 p1 = p2
e) 2 p1< p2

Answer 1

Remember that atmospheric pressure is always added to a term that is proportional to depth. That should help you choose the correct answer.

Answer 2

so its d right

Answer 3

d) is NOT right. You ignored what I said about the atmospheric pressure term that gets added
