Question

1. static electricity is caused by an imbalance of electric charge. when positive charges build up on an object, the object has a net positive charge. when negative charges build up on an object, the object has a net positive / negative / neutral charge. an electric discharge happens when an object loses its extra negative charges. the positive and negative charges in an object are equal after a complete discharge, so the object has a net positive / negative / neutral charge.

Explanation:

1. For the first blank: The text states negative charges building up create a net negative charge, matching the structure of the positive charge example.
2. For the second blank: A complete discharge equalizes positive and negative charges, resulting in no net charge (neutral).

Answer:

1. negative
2. neutral
