| Dec 27, 2014 at 18:24 | comment | added | ProfRob | @user54609 What does it matter how big the scale is? I think you don't know what your question is. Just because you make an instrument smaller, doesn't mean it measures wrong. | |
| Dec 27, 2014 at 18:18 | comment | added | ithisa | @RobJeffries: The scale on the meter is shrunken too. I guess my question is actually "how to measure lengths when all the scales are shrunken in proportion" | |
| Dec 26, 2014 at 20:38 | comment | added | ProfRob | It's the size of the force that is the issue, not the size of the force-meter! | |
| Dec 26, 2014 at 20:02 | comment | added | ithisa | How can you use a force meter? Assume that the force meter is, too, shrinked in proportion. | |
| Dec 26, 2014 at 14:24 | comment | added | pentane | The idea of using a macroscopic force meter to measure the repulsion between two electrons is just too funny to not upvote this. +1 | |
| Dec 26, 2014 at 13:37 | comment | added | Random832 | What happens to the force-meter when you shrink it? i.e. assume that the component parts, e.g. the spring and the marked scale, are shrunk down, and behave in a way that the person holding it cannot tell the difference. | |

| Dec 26, 2014 at 6:35 | comment | added | CuriousOne | Good luck measuring the force between two electrons with a force gauge. You could, of course, measure the force between some 1e14 electrons or so... it would be on the order of 1N. Now all you need to do, is to count 1e14 electrons. I think I stick to counting 10,000 fringes. :-) | |

| Dec 26, 2014 at 5:32 | comment | added | CuriousOne | What are you using to measure a force? Force is defined trough the acceleration of a mass. You need a ruler and a clock to measure acceleration... | |
