Question 3

Electric Charge is measured in?

Answer 3

Coulombs (C)

Question 4

Charges may either be _________ or __________

Answer 4

positive or negative

Question 5

1e=?

Answer 5

1.602 x10^-19 C

Question 6

Everyday objects contain?

Answer 6

contain as much positive charges as negative
charges meaning they are neutral

Question 7

How do objects become charged?

Answer 7

An object become charge if there is an IMBALANCE in the amount of charges it possesses

Question 8

What causes this imbalance?

Answer 8

Simple activities such as rubbing your clothes affect the amount of charges in the cloth. This is charging by friction.

Question 9

3 types of charging

Answer 9

Friction
Induction
Conduction

Question 10

occurs when two objects rub against each other, causing a transfer of electrons and resulting in the generation of static electricity.

Answer 10

Friction

Question 11

• involves the contact of a charged object to an initially neutral object.
• In this method, both objects acquire the same type of charge

Answer 11

Conduction

Question 12

involves the polarization of charges in an initially neutral object when a charged object is brought near it

Answer 12

Induction

Question 13

2 laws of charge

Answer 13

like charges REPEL
unlike charges ATTRACT

Question 14

The force between two charges in space is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them.

Answer 14

Coulumb’s Law
