What is the nucleus?
Transferring electrons to an object by touching it is known as this.
What is charging by contact? (electrons flow from more negative to less negative)
If the two charges are opposite in sign, then this can be said of the electrical force with regard to sign and direction.
What is the force will have a negative sign and the force is attractive?
A material that allows capacitors to have greater capacitance by allowing the plates to be closer together.
Dielectric
Electric force, electric field, and electric field lines are all one of these.
Vectors
When an atom has equal number of protons and electrons, the atom is said to be this.
What is neutral or uncharged?
Making an uncharged object have charged by bringing a charged object close to it but not touching is known as this.
What is charging by induction?
If the two charges being considered are both positive or both negative, then this can be said of the electrical force with regard to sign and direction.
What is the sign of the electrical force is positive and this force is repulsive?
The way a capacitor stores electric energy.
By separating the positive and negative charges
