How a Space Telescope’s Accidental Discovery Overturned Everything we Thought we Knew About Lightning Storms
Coulomb’s Law in Space:
The “Nitten-Needle” Video for the Space Station. As the force between charged particles obeys Coulomb’s Law, which is an inverse-square law, these charged water droplets orbit the oppositely charged needle just as a spherical mass would orbit a cylindrical planet due to gravity. F is proportional to 1/r^2 in both cases.
