The two oppositely charged metal spheres in FIGURE have equal quantities of charge. They are brought into contact with a neutral metal rod. What is the final charge state of each sphere and of the rod? Use both charge diagrams and words to explain.
Final charge state of each sphere and of the rod is neutral.
Initial state diagram showing two charged spheres and a neutral metal rod that are not yet in contact.
Because all three objects are metals (two spheres and one metal rod), they are charge and electricity conductors.
Because spheres have an equal amount of opposing charge, when they come into contact with a neutral metal rod, electrons will transfer from a negatively charged sphere to a positively charged sphere through the metal rod until the entire system reaches electrostatic equilibrium.
Due to an equal quantity of opposite charge in the initial state, the system as a whole will be in a neutral state.
When there is a constant between two spheres over a metal rod and electrons, the system as a whole has a neutral charge.
Suppose there exists a third type of charge in addition to the two types we’ve called glass and plastic. Call this third type charge. What experiment or series of experiments would you use to test whether an object has charge? State clearly how each possible outcome of the experiments is to be interpreted.
A negatively charged electroscope has separated leaves.
a. Suppose you bring a negatively charged rod close to the top of the electroscope, but not touching. How will the leaves respond? Use both charge diagrams and words to explain.
b. How will the leaves respond if you bring a positively charged rod close to the top of the electroscope, but not touching? Use both charge diagrams and words to explain
