Electric Fields Flashcards
1
Q
What is an electric field?
A
The region in which an electric charge experiences a force
2
Q
What is Coulombs Law of Force?
A
The magnitude of the force between two point charges which are a distance apart is directly proportional to the product of the charges and inversely proportional to the square of their distances apart
