What is the force between two point charges via Google?
Click For Summary
Discussion Overview
The discussion revolves around the calculation of the force between two point charges using Coulomb's law, as well as the functionality of Google as a computational tool for physics-related queries. Participants explore the use of different units and the effectiveness of Google in performing these calculations.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Warren shares a Google search link to calculate the force between two charges using Coulomb's law.
- Monique questions the purpose of the calculation, prompting a discussion about its significance.
- Warren expresses enthusiasm for the calculation and suggests it is a simple application of physics.
- Monique acknowledges Warren's creativity in approaching the calculation.
- Warren humorously suggests using unconventional units for calculations, indicating a playful attitude towards the topic.
- Participants note the built-in calculator feature of Google, with one expressing surprise at its capabilities.
- Warren mentions a specific calculation result using Coulomb's law but notes issues with unit conversions, particularly with nanocoulombs.
- Another participant points out that "nanocoulombs" works in a Google search, while "nC" does not, raising questions about input rules.
Areas of Agreement / Disagreement
Participants express varying levels of interest and understanding regarding the calculation, but there is no consensus on the significance of the calculation or the rules for input in Google searches.
Contextual Notes
There are unresolved questions about the input formats accepted by Google for calculations involving different units of charge.

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:"
