Question

Which of the following factors does not affect the pressure at a point inside a liquid?

• A. Depth of the point from the surface
• B. Acceleration due to gravity
• C. Shape of container the liquid is kept in
• D. Density of the liquid

Answer 1

The correct option is C

Shape of container the liquid is kept in

The pressure at any point inside a liquid is given by,

Pressure = d$\times$g$\times$h

Where ‘d’ is the density of the liquid, ‘g’ is the acceleration due to gravity and ‘h’ is the depth.

The explanation for the correct answer:

The pressure at a point inside a liquid depends upon the following factors:

1. Depth of the point from the surface, with the increase in depth the pressure increases and vice-versa
2. Acceleration due to gravity. The pressure inside a liquid depends on the value of acceleration due to gravity 'g' = 9.8 m/s² , which is a constant.
3. Density of the liquid. With the increase in the density of the liquid the pressure inside the liquid increases and vice-versa.
4. However, the pressure inside the liquid doesn't depend upon the shape of the container the liquid is kept in.

Thus, option (C) is the correct option.
