The force newton(N),between two particles is inversely propotional to the square of the distance ,d m,between them.When particle

bonufazy [111]

Answer: $1.6\ N$

Step-by-step explanation:

Given

The force between the two particles is inversely proportional to the distance between them

$\Rightarrow F\propto \dfrac{1}{d^2}$

When the distance is 2 m, the force is 10 N. For 5 m distance, it is

$\Rightarrow \dfrac{10}{F_o}=\dfrac{5^2}{2^2}\\\\\Rightarrow F_o=10\times \dfrac{2^2}{5^2}\\\\\Rightarrow F_o=1.6\ N$

Thus, the force between them is $1.6\ N$

Papessa [141]

we know that

by proportion

$\frac{18,000}{900} \frac{\$}{feet}= \frac{x}{60}\frac{\$}{feet} \\\\ 900*x=18,000*60 \\\\x= \frac{18,000*60}{900}\\\\ x= \$1,200$

therefore

<u>the answer is</u>

$\$1,200$
