the negative charge distribution over the surface of two isolated spheres is depicted in the diagram. one of the spheres is made of copper and the other is of rubber. identify the sphere that depicts the charge distribution of copper and that of rubber. support the answer with an explanation.(on the paper it has 2 spheres a and b shere a has 9 dark spots and 1 faded and all ofer the sphere. sphere b has 10 dark spots and its organized not all over. i don't understand this question and its bothering me. thank you

• physics -

Sphere A: Is Rubber it is an insulator, and that means the electrons are all in there one space. That's the dark spots you were talking about. Sphere B: Is Copper and it is a conductor; the electrons are all over the sphere. As is the opposite to the sphere A. And this concludes the exact opposites of how insulators and conductors are.
