Question

Pressure exerted by a liquid is due to its

• A. Force
• B. Mass
• C. Weight
• D. None of these

Answer 1

The correct option is C

Weight

1. At various depths, a liquid has a variable pressure.
2. As the depth deepens, pressure rises.
3. The weight of the water column above is what causes the pressure in a liquid.
4. This pressure works in all directions because a liquid's particles are closely packed.
5. For instance, the pressure exerted on a dam at a reservoir's bottom is larger than the pressure exerted near the top.
6. Dam walls are typically wedge-shaped for this reason.
7. The increased "force per unit area" on the wall would result from the higher pressure at the bottom.

Thus, the pressure exerted by a liquid is due to its weight.

Hence, option C is correct.
