Question

Use the drop-down menus to answer each question. How do objects with the same charge interact? How do objects with opposite charges interact? How do uncharged objects interact?

Answer 1

It's very tough to use the drop-down menus for this.  I'll just do the best I can without them.

-- Objects with the same charge repel each other with electrostatic force, and attract each other with gravity.  You can ignore the gravity because the electrostatic force is so much stronger.

-- Objects with opposite charge attract each other with electrostatic force, and also attract each other with gravity.  You can ignore the gravity because the electrostatic force is so much stronger.

-- Objects with no charge have no electrostatic force between them, and they only attract each other with gravity.
