Question

If the pressure due to liquid varies with the depth
y as shown in figure, then the density of the liquid
is (g = 10 m/s2)
​

Answer 1

Slope of straight line is

depth(h)

Pressure

.

We know that pressure at a depth of h is P = ρgh,

where P is pressure at a depth of h,

ρ is the density of liquid.

g is acceleration due to gravity.

h is liquid column depth.

So,

h

P

=ρg.

So, slope of the straight line is ρg.

Answer 2

Answer:

Slope of straight line is  

depth(h)

Pressure

​

.

We know that pressure at a depth of h is P = ρgh,

where P is pressure at a depth of h,

ρ is the density of liquid.

g is acceleration due to gravity.

h is liquid column depth.

So,  

=sp a slope of the line is an a straight line
