Question

With the increase in the area of contact of an object, the pressure:
(Note : Thrust remains same)

• A. Increases
• B. Decreases
• C. Is not affected
• D. None of these

Answer 1

The correct option is B Decreases

Since,
$P=\frac{F}{A}$
Thus pressure is inversely proportional to area,
$i.e.P\propto \frac{1}{A}$

With the increase in the area of contact of an object the pressure decreases because pressure is inversely proportional to area of contact.
