Question

Pressure varies with area $\left(\mathrm{A}\right)$ as :

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

Answer 1

The correct option is B

$1/\mathrm{A}$

Explanation

1. Pressure is defined as force per unit area.
2. $Pressure=\frac{Force}{Area}$
3. Hence pressure is inversely proportional to area.
4. $P\alpha \frac{1}{A}$

The correct option is (B).
