Electromagnetism: testing Coulomb’s law
...data from these experiments after you’ve watched this video. So what we’ll do next is put 30 nanocoulombs of charge on the test charge and on sphere A. Now I’ll record the readings, and you should see them appear on your screen. The values in millinewtons are 0.62, 0.63, 0.65, 0.64, 0.68 and 0.69. Now we’ll ground these two spheres. So I’ll use an earth rod and...
