Which all of the following are true about liquid pressure?
Which all of the following are true about liquid pressure?
The correct options are
A Inside the liquid, pressure increases with the increase in depth from its free surface.
B In a stationary liquid, the pressure is same at all points on a horizontal plane.
C Pressure is the same in all directions about a point inside the liquid.
The following are true
i) Inside the liquid, pressure increases with the increase in depth from its free surface. The pressure at depth h is given by ρgh where ρ is density and g acceleration due to gravity
ii) In a stationary liquid, the pressure is the same at all points on a horizontal plane.
iii) Pressure is the same in all directions about a point inside the liquid.
iv) Pressure is defined as force per unit area. Liquids exert force due to their weight which will create pressure. so option D is incorrect.
