Like charges or poles

• attract
• repel
• do nothing

If an object has more positive charges than negative charges, the net charge is 

• neutral
• positive
• negative

When the domains in an object align, the object 

• does not change
• becomes magnetic
• becomes electric

What option best describes this field?

• A strong electric field generated by two positive charges. They would attract each other.
• A strong electric field generated by two positive charges. They would repel each other.
• A weak electric field generated by two opposite charges. They would attract each other.
• A weak electric field generated by two positive charges. They would repel each other.
