Final answer:
A positively charged object will attract an uncharged object, while a negatively charged object will repel an uncharged object.
Step-by-step explanation:
When a positively charged object is placed near an uncharged object, the uncharged object will be attracted to the positively charged object. This is because the positively charged object has an excess of positive charges, which creates an electric field that attracts the negative charges in the uncharged object.
On the other hand, when a negatively charged object is placed near an uncharged object, the uncharged object will be repelled. This is because the negatively charged object has an excess of negative charges, which creates an electric field that repels the negative charges in the uncharged object.
For example, if a positively charged glass rod is brought near an uncharged ball, the ball will be attracted to the glass rod. If a negatively charged plastic rod is brought near the same uncharged ball, the ball will be repelled by the plastic rod.
