any same length uncharge objects different charged objects repelled point-like attached angle torsion balance Charles Coulomb determined the dependence of the force between separation. The experimental apparatus he used is called a(an) Coulomb hung a light glass rod from a thin wire. At the ends of the rod he metal spheres. He then charged a third metal sphere and touched one of the spheres the rod. on the distance of The two spheres consequently had the electric charge, and they wire twisted until the torque exerted by the wire on the glass rod balanced the torque exerted by one charged sphere on the other. The Coulomb's expression is used for identical small objects. The Coulomb measured the of this twist and used it to determine the electric force exerted by one sphere on the other. He measured the distance between the repelling spheres and varied it to see how the force of repulsion depended on the distance between them. to

Static electricity demonstrations  I need to draw diagrams for each questions  a. piece of rabbits fur and black plastic rod. The rabbits fur has a lower electron affinity and the rod has a higher electron affinity.  Draw the black plastic rod and diagram it with the imbalance of charge that exists. Also put a little explaining on how it got the charge. b. black plastic rod near a metal spear attack to a insulating handle I'm making no contact to the sphere what so ever. I'm going to take the charged object and touch it to the neutra sphere. I need to diagram that process when I touched it and I need to show what happens to the sphere in the situation. I need to make sure I show the movement of charge and also what kind of charging that was.  c. Metal sphere same charge as before and I'm going to bring it near a already charged electroscope.  I'm going to bring the sphere near the electro scope button, and when I do that you can see what happens to the leave and when I bring it back…
