Students are planning an investigation into the distribution of charges in insulators and conductors. They know that charges can be transferred by conduction, induction, and friction. What materials and tests would they need to choose in order to identify conductors and insulators using conduction, induction, and friction?

A. Students need to choose metals and nonmetals. They would need to perform tests where materials are only touching non-charged objects, but not coming into the electric field of charged objects.

B. Students need to choose only metals. They would need to perform tests that include the touching of materials to charged objects, materials within the electric field range of
charged objects, and use some sort of force to cause friction to occur with materials.

C. Students need to choose metals and nonmetals. They would need to perform tests that include touching of materials to charged objects, materials within the electric field range of charged objects, and use some sort of force to cause friction to occur with materials.

D. Students need to choose only nonmetals. They would need to perform tests that include the touching of materials to charged objects, materials within the electric field range of charged objects, and use some sort of force to cause friction to occur on materials.
