Question

2) If pressure of a liquid is 1000 Pa and height of the liquid is 20 cm, then density of the liquid is
(keeping in mind the gravitational pull of earth)
a)50 g cm
b)5 g cm
c)100 g cm
d)0.2 g cm
​

Answer 1

Answer:

b)5 g cm

Explanation:

Answer 2

Density of liquid is B) 5g/cm³

Pressure is defined as perpendicular force applied to any object per unit area. Fluid pressure is the pressure applied on object immersed in fluid.

Since fluids do not have particular shape, hence forces apply on all directions on object.

Pressure is calculated by the formula P = rho*g*h

P is pressure, rho is density, g is acceleration due to gravity and h is height.

Rho = 1000/10*0.2

Rho = 5000 kg/m³

Rho = 5g/cm³

Hence, density is 5g/cm³.
