Electrostatic force, Newtons and Distance

Click For Summary
SUMMARY

The discussion centers on calculating the distance between two protons based on the electrostatic force of 1x10^-7 Newtons. Using Coulomb's law, represented by the formula F = kq1q2/r^2, participants highlight that the distance r can be derived using the equation r = sqrt(kq1q2/F). Constants for k (Coulomb's constant) and the charge of protons (q1 = q2) are essential for this calculation.

Have a problem that I'm not sure how to approach any help would be appreciated!

If the electrostatic force between two protons is equal to 1x10^-7 Newtons, what is the distance between them?

F = kq1q2/r^2

Given F, and k, q1 = q2 = a constant you have to look up, you can find r...

r = sqrt(kq1q2/F)
