You have an object with an unknown electric charge. In other words, it could be neutral, negatively charged, or positively charged. You make two observations about this object.

1. The object of an unknown charge is attracted to a negatively charged rod when you move the rod close to, but not touching, the object.

2. The object of an unknown charge is attracted toward a positively charged rod when you move the rod close to, but not touching, the object. What conclusion can you make about the unknown charge, having made these two observations?
