AfilCa [17]

Answer:

The correct answer is "3899.92 N".

Explanation:

The given values are:

Force,

$F_{app}=58 N$

Ratio,

$\frac{R_2}{R_1}=8.2$

As we know,

Area, $A=\pi r^2$

or,

⇒ $\frac{F_2}{F_1} =\frac{A_2}{A_1}$

On substituting the value of "A", we get

⇒ $\frac{F_2}{F_1} =\frac{\pi r_2^2}{\pi r_1^2}$

⇒ $\frac{F_2}{F_1} =\frac{r_2^2}{r_1^2}$

On applying cross-multiplication, we get

⇒ $F_2=F_1\times (\frac{r_2}{r_1} )^2$

On substituting the given values, we get

⇒ $=58\times (8.2)^2$

⇒ $=58\times 67.2$

⇒ $=3899.92 \ N$
