Question

7b. a group of students are conducting an investigation about charging through the process of friction. the students rub two neutral materials together, and there is a transfer of electrical charge from one material to the other. what is the resulting, net electrical charge of the materials in this system? the net electrical charge is positive as electrons are transferred from one material to the other. the net electrical charge is positive as protons are transferred from one material to the other. the net electrical charge remains neutral as electrons are transferred from one material to the other. the net electrical charge remains neutral as protons are transferred from one material to the other.

Explanation:

This is based on the law of conservation of electric charge, which states that charge can be transferred between objects but cannot be created or destroyed. In friction charging, only negatively charged electrons move between neutral materials; protons are bound in the nucleus and do not transfer. When electrons move from one neutral material to another, the material that loses electrons becomes positively charged, and the one that gains electrons becomes negatively charged. The total positive and negative charges in the system cancel out, so the net charge of the entire system remains neutral.

Answer:

The net electrical charge remains neutral as electrons are transferred from one material to the other.
