1 What is a vector field? 2 How do you know that potential energy is converted into kinetic energy in certain force fields?

3 What is the rule on electric charges attracting or repelling?
Opposites attract, equals repel

4 How can atoms use electric charges to bond?

5 Where is the potential energy of a magnet stored?

6 How can you tell which pole is the north and which pole is the south in a magnet?

7 How can you increase the potential energy of a magnetic field?

8 If you have two charges alone in space, what will they do to each other?

9 What must occur in magnets to have it generate a magnetic field?

10 What is an electromagnet? A magnet that is made from metal and electrified and with a coil

1. a vector field is an assignment of a vector to each point in a subset of space.

2. The direct answer is that it happens through Newton’s second law. If an object is in a potential field that is different at different points in space, then the object will experience a force in the direction in which the potential energy decreases. Newton’s second law says that a force causes a change in motion, which changes the kinetic energy.

3. According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

4. Ions are charged atoms that form when an atom donates or accepts one or more negatively charged electrons. Cations (ions with a positive charge) are attracted to anions (ions with a negative charge). This attraction is called an ionic bond.

Hope it Helps

double the distance = divide strength by 4

i believe the answer would be:
