Question

8 multiple choice 3 points look at the wall. what is the net charge on the wall? more positive than negative charges zero -- equal number of positive and negative charges more negative than positive charges

Explanation:

In general, most objects (including walls) are electrically neutral under normal conditions. This means they have an equal number of positive (protons in the nuclei of atoms) and negative (electrons) charges. The positive and negative charges cancel each other out, resulting in a net charge of zero.

Answer:

Zero -- equal number of positive and negative charges
