What is the force between two point charges via Google?
Click For Summary
SUMMARY
The discussion centers on using Google as a calculator for physics equations, specifically Coulomb's Law, which calculates the force between two point charges. Participants highlight the formula (-8 C) / (4 * pi * epsilon_0 * (2.45967 m)^2) to derive the force in Newtons per Coulomb. Users note that while the calculation works with meters, it fails with nanocoulombs (nC), prompting questions about input rules for the Google calculator. The conversation emphasizes the utility of Google as a built-in calculator for various scientific computations.
PREREQUISITES- Understanding of Coulomb's Law
- Familiarity with electric constants and units

I do, I am impressed you are so creative..
(-8 C) / (4 * pi * electric constant * ((2.45967 m)^2))?
Try this one:

NOW I'm impressed

The equation I entered was actually just Coulomb's law -- a simple equation in physics to find the strength of an electric field.
Hehehehe... how about some wacky units?

Wow, a built-in calculator for google. Never noticed it. Fascinating.

Google is an amazing search engine. I especially like the Groups and News Section.
To top it all off, the whole site runs on Linux, which automatically makes it even cooler.

(-8 C)/(4*pi*epsilon_0 *(2.45967 m)^2) in (Newtons/coulomb)
(-8 C) / (4 * pi * electric constant * ((2.45967 m)^2)) = -1.18844121 ¡Ñ 1010 Newtons / Coulomb
How clever !
However when I tried this, it couldn't calculate the answer for me. When I changed m (meter) to mm, it worked fine. But when I changed C to nC, it didn't work.
Is there any rule for the input?

I'm not sure why it doesn't like nC, but it's fine with "nanocoulombs:"
