Answer:
Positively charged objects attract negatively charged objects,
Explanation:
When there are two electric charges, the force between them is:
- repulsive if the two charges have same sign (positive-positive or negative-negative)
- attractive if the two charges have opposite signs (positive-negative)
Moreover, a neutral object does not exert/experience any force on/from charged objects.
Keeping in mind these facts, we have:
Positively charged objects attract other positively charged objects, --> false, force is repulsive
Negatively charged objects attract other negotively charged objects --> false, force is repulsive
Positively charged objects attract negatively charged objects, --> true, force is attractive
Positively charged objects attract neutral objects, --> false, there is no force
Negatively charged objects attract neutral objects --> false, there is no force
