If you stand on loose sand and if you lie down on the sand, you will find that in both the cases the force exerted on the sand is the weight of your body. Choose the correct answer regarding above cases from the following options.

Pressure exerted on sand is more when you stand on loose sand.

When you stand on loose sand, the force, that is, the weight of your body is acting on an area equal to area of your feet.

When you lie down, the same force acts on an area equal to the contact area of your whole body, which is larger than the area of your feet.

Thus, the effects of forces of the same magnitude on different areas are different.

In the above cases, thrust is the same. But effects are different.

Therefore, the effect of thrust depends on the area on which it acts.

The effect of thrust on sand is larger while standing than while lying.

The thrust on unit area is called pressure.

Pressure = \(\frac{Thrust}{Area}\)
