Question

Alguem pode me ajudar a resolver essas questões????? Por favor

Answer 1

$\boxed{F=Ko\frac{|Q1*Q2|}{d^2}}$

Questão 1:
$d=3cm=0,03m=3*10^{-2}$

$\boxed{F=Ko\frac{|3*10^{-6}*3*10^{-6}|}{(3*10^{-2})^2}}$
$\boxed{F=Ko\frac{9*10^{-12}}{9*10^{-4}}}$
$\boxed{F=Ko\frac{1*10^{-12}}{1*10^{-4}}}$
$\boxed{F=Ko*1*10^{-8}}$
$\boxed{F=9*10^{9}*1*10^{-8}}$
$\boxed{F=90*10^{8}*1*10^{-8}}$
$\boxed{\boxed{Resposta-Q1:F=90N}}$

Questão 1:
$d=15cm=0,15m=15*10^{-2}$

$\boxed{F=Ko\frac{|3*10^{-5}*5*10^{-6}|}{(15*10^{-2})^2}}$
$\boxed{F=Ko\frac{15*10^{-11}}{15*15*10^{-4}}}$
$\boxed{F=Ko\frac{1*10^{-11}}{1*15*10^{-4}}}$
$\boxed{F=Ko\frac{1*10^{-7}}{15}}$
$\boxed{F=9*10^{9}*\frac{1*10^{-7}}{15}}$
$\boxed{F=\frac{9*10^{2}}{15}}$
$\boxed{F=\frac{900}{15}}$
$\boxed{\boxed{Resposta-Q2:F=60N}}$
