Solution
The correct option is
C
the area of the liquid surface
Let the acceleration of tank be
a
(
moving up
)
,
Let the density of the liquid be
d
and height of liquid be
h
,
The pressure at the bottom of tank is
P
=
P
0
+
d
h
(
g
+
a
)
,
Therefore the pressure depends on acceleration, height of the liquid and the density of liquid.
It does not depend on the area of the liquid surface,
Therefore correct option is
C
.
