Chapter 5. Electricity and magnetism

Question 1

What is an electric field?

Answer 1

The space surrounding a charged body is called an electrical field. A charged body entering an electrical field will be subject to electrostatic force.

Question 2

When drawing electric field diagrams, the arrows around the negatively charged objects…

Answer 2

Move in and towards it

Question 3

When drawing electric field diagrams, the arrows around the positively charged objects…

Answer 3

Move out and away from it

Question 4

What does static electricity describe?

Answer 4

All phenomena related to electrical charges at rest and insulated charges.

Question 5

What are the three ways to charge an object?

Answer 5

1. Friction
2. Conduction
3. Induction

Question 6

The only charges that can move between objects are…

Answer 6

negative

Question 7

What does charging by friction mean?

Answer 7

When two neutral bodies are rubbed agaisnt each other, some atoms in one of the bodies may pull electrons away from the atoms of the other body, creating two objects with different charges

Question 8

What determines the object that is able to receive the electrons?

Answer 8

The object’s tendency to capture or give up electrons

Question 9

What does charging by conduction mean?

Answer 9

A conductor can be electrically charged by putting in it contact with another conductor that is already charged

Question 10

What is charging by conduction result in?

Answer 10

Two objects will have the same type of charge but with magnitude less than that of the original charged object
