MCQ
The same force $“F”$ acts on four different objects having the areas given below, one by one. In which case the pressure exerted will be the maximum?
- A$20m^2$
- B$50m^2$
- ✓$10m^2$
- D$100m^2$
✓
Answer
Correct option: C.
$10m^2$
The force $“F”$ is all the same in all situation making it constant.
Using the formula: pressure $=$ force$/$area.
This suggest that since $“F”$ is constant, decrease in area will lead to increase in pressure and vice vasa. This may be represented by a real$-$life example with a sharp healed shoe of a lady and a normal shoe. If a lady weighing $140N$ may step on you while wearing the sharp healed shoe, the pain will be more severe than while wearing a normal flat shoe. Therefore, the lesser the area, the greater the pressure. Hence, your answer will be $10m^2.$
