Like charges attract.
Opposite charges repel.

A positively charged object has gained protons.
A negatively charged object has lost protons.
A negatively charged object has gained electrons.
Answer: ADEH
A and D are true; they are the simple statement of our essential charge interactions, best remembered by the jingle: "opposites attract, likes repel."
B and C are false for these same reasons; they violate the basic statement of charge interactions.
E and H are true. For an object to become charged, it must either gain or lose electrons. Losing electrons results in more positive charge than negative charge, making the object charged positively. Gaining electrons results in more negative charge than positive charge, making the object charged negatively. Protons are tightly bound in the nucleus of atoms and can never be added nor removed from atoms by ordinary electrostatic methods. The same reasoning leads one to reject choice F and G as possible true statements; the suggest that protons can be added or removed.
Answer: electrically charged objects can be charged by being rubbed together with an electrically charged object.
Explanation: it is attracted to the balloon because it is obviously electrically charged. if an object is charged and the other is not they will be attracted to each other.
also to add to that... The balloon is attracting the paper because the balloon is charged positively and the paper is uncharged or is charged positively. This is an example of how an electrically charged object can attract an uncharged object without any contact. When an uncharged object is close or rubs together with an uncharged object they pull together. (rub because when they rub together they become equally charged)
