Electrostatic Electrostatic force Force Newtons

AI Thread Summary

To determine the distance between two protons given an electrostatic force of 1x10^-7 Newtons, the formula F = kq1q2/r^2 can be rearranged to solve for r. By substituting the known values of F and the constants k and q1 = q2, the distance can be calculated using r = sqrt(kq1q2/F). This approach allows for the precise calculation of the distance based on the electrostatic force and the charges involved. Understanding these principles is essential for solving electrostatic problems in physics. The discussion emphasizes the importance of applying the correct formula to find the desired distance.

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)

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev
