RQ1-1. A charged balloon sticking to a wall does not mean the wall is charged. The negative charge on the balloon induces a positive charge on the surface of the wall, which causes the wall and balloon to be mutually attracted to each other.

RQ1-2. Two charged balloons would repel each other because they would both be negatively charged.

RQ1-3. The U tape is _________________ charged because when I brought a rubber rod near it, then a charged glass rod near it, the _____________ rod is the one that repelled it, hence it has the same charge that this rod has.

RQ1-4. The statement in RQ-4 is false because one cannot remove protons from nuclei of atoms because they are so tightly bonded to the neutrons. If this were to occur, the carbon would be changed into another element.

RQ1-5. A proton must have a total charge of +1 e, so it must be made up of 2 up quarks and one down quark.

2 (2/3)e + (-1/3)e = 1e

A neutron must have a total charge of 0, so it must be made up of 2 down quarks and one up quark.

2(-1/3)e + (2/3)e = 0

RQ1-6. No experiment has been ever been performed that demonstrates charge being transformed into energy.

RQ1-7. Do electric forces pass thru objects? Yes, we demonstrated this using a paper shield. However, the force appeared to diminish because the superposition principle enabled the charge induced in the paper by the charged object to exert an opposite force on the other object on the other side of the paper.

RQ1-8. Yes, these forces are an "action - reaction " pair.
