Question

The value of $P=20Pa$ and the value of $A=0.5m^2$. Find out the value of $F$.

• A. $20N$
• B. $10N$
• C. $5N$
• D. $40N$

Answer 1

The correct option is B $10N$

Given:
$P=20Pa$ and $A=0.5m^2$
According to the Pascal's Law:
$P_1$ = $P_2$
$P$ = $\frac{F}{A}$
$F$ = $P\times A$
$F$ = $20\times 0.5$
$F$ = $10Pa$
