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