Question

A bottle kept on a table started leaking at equal rates when two holes were made at the same level. This is because_______.

• A. the liquid exerts equal pressure in all directions at the same level
• B. the liquid does not exert any pressure
• C. the liquid exerts unequal pressures in different directions at the same level
• D. the liquid exerts pressure only at one hole and not at the other hole

Answer 1

The correct option is A

the liquid exerts equal pressure in all directions at the same level

The pressure at any point in a liquid is because of the weight of the overlying liquid column. It depends on the depth of the point from the upper surface. Hence, for equal depths, the fluid exerts equal pressure in all directions. When holes are at the same level, the pressure exerted by the fluid molecules at the holes will be the same. Hence, the liquid will flow at the same rate.
