Duas cargas elétricas opostas tem uma força de atração de 2,7 kn e possuem cargas de modulo de 25 µc e 30 µc. qual é a distância entre elas?
Answers: 3
is the Coulomb's constant 
, 
and 
are the signed magnitudes of the charges, and 
is the distance between the charges.
![r=\sqrt{9x10^{9}N.m^{2}/C^{2} \frac{[25x10^{-6}C ] [30x10^{-6}C] }{2.7x10^{3}N }}\\r= 0.05m](/tpl/images/0490/7089/49a9b.png)
