Homework Statement
1)Coulomb's law states that the electric force becomes weaker with increasing distance. Suppose that instead the electric force between two charged particles were independent of distance. In this case, would a charged comb still cause a neutral insulator to become polarized? why or why not? Would a neutral insulator still be attracted to the comb? why or not why?
2)Two metal spheres are hanging from nylon threads. When you bring the spheres close to each other, you notice that they tend to attract. Is it possible that after the spheres touch, they will cling together? why or why not?
Homework Equations
The Attempt at a Solution
Here are my attempts. Please correct me if I'm wrong and elaborate on why I'm right if I'm right.
1)If the electric forces between two charged particles were independent, would this mean the amount of force will be the same anywhere? If this is the case, the charged comb will cause the neutral insulator to become polarized because there is a electric force acting on it and the insulator will be attracted to the comb.
2)I don't really get how induced charges work. Are the protons and electrons positioning themselves so that the spheres will be polarized? if they touch, wouldn't charges be transferred to each sphere to neutralize them. If this is true, then they can't cling together. I need someone to explain this to me
