Which of the following statements is true about the hydrostatic pressure? (i) Pressure increases with height (ii) Pressure is independent of the shape and volume of the vessel (iii)Pressure is the same at all points on the same horizontal plane in a fluid (iv)Pressure is independent of the surface area in contact
A. (i), (ii), (iii) and (iv) B. (i), (ii), and(iii) only C. (ii), (iii) and (iv) only D. (i), (ii), and (iv) only
Correct Answer: A
Explanation
Pressure in liquid (water) is called hydrostatic pressure. All the statements are true for hydrostatic pressure. Mathematically, Hydrostatic pressure \(=\rho g h\) \(g=\) acceleration due to gravity \(\rho=\) density of fluid \(h=\) depth
