Question

Pressure varies with force as :

• A. $\mathrm{F}$
• B. $1/\mathrm{F}$
• C. ${\mathrm{F}}^2$
• D. $1/{\mathrm{F}}^2$

Answer 1

The correct option is A

$\mathrm{F}$

Explanation

The force exerted perpendicular to an object's surface per unit area over which it is distributed.

$Pressure=\frac{Force}{Area}$

$\mathrm{P}=\frac{\mathrm{F}}{\mathrm{A}}$

So, $\mathrm{P}\alpha \mathrm{F}$

Where, area ($\mathrm{A}$) is constant, pressure is directly proportional to force ($\mathrm{F}$).

Hence, correct option is (A).
