Which of the following statements about the forces between charged objects is not true?
As the distance between charged objects decreases, the electric force between them decreases.
If one object is positively charged and another is negatively charged, the objects will attract each other.
Two negatively charged objects will repel each other.
As the amount of charge on either object decreases, the electric force between them decreases.

A student created an electromagnet out of a piece of copper wire, a nail, and a battery, as shown.
The student observed that the electromagnet could not lift paper clips off a desktop as expected. Which hypothesis will most likely help the student build an electromagnet capable of lifting paper clips?
Using a wooden stick instead of a nail will increase the number of paper clips that the electromagnet can pick up.
Adding more coils of copper wire to the nail will increase the number of paper clips that the electromagnet can pick up.
Pushing the coils of copper wire closer together will increase the number of paper clips that the electromagnet can pick up.
Using a battery that produces less electric current will increase the number of paper clips that the electromagnet can pick up.
During an investigation, a teacher places a small permanent magnet with a hole in it onto a wooden rod. The magnet can slide freely up and down the rod. When the teacher places the magnet and rod on a tabletop above an electromagnet, the magnet slides up the rod as shown in the diagram.
How does the size of the magnet affect the distance the magnet travels up the rod?
How does the distance between the magnet and the electromagnet affect the strength of the magnetic force of the electromagnet?
How does the amount of the electric current affect the distance the magnet travels up the rod?
How does the direction of the electric current affect the strength of the magnetic force of the electromagnet?
