Two small charged spheres are 6.52 cm apart. They are

Step 1 of 3 

We are asked to find the distance between two charged spheres if the force between them is three times the force between the spheres when they were 6.52 cm apart

From Coulomb’s law:

Force between two charged particles is given as, 

\(F=\frac{k q_{1} q_{2}}{r^{2}}\)

Where, 

\(q_{1}\) and \(q_{2}\) are charges, and r the distance between them. 

\(k=\frac{1}{4 \pi \epsilon_{o}}\) is the proportionality constant.
