Detailed explanation-1: -The electric force is a non-contact force. Any charged object can exert this force upon other objects-both charged and uncharged objects.
Detailed explanation-2: -The phenomenon we recognize as “static electricity” has been known since ancient times. It was later found that there is a physical quantity known as electric charge that can be transferred from one object to another. Charged objects can exert forces on other charged objects and also on uncharged objects.
Detailed explanation-3: -Positive and negative charged objects attract or pull each other together, while similar charged objects (2 positives or 2 negatives) repel or push each other apart.
