electrical fields and coulomb's law Flashcards
1
Q
Coulomb’s Law
A
Two point charges in free space or air exert forces on each other. The force
is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
2
Q
Electrical field
A
A region of space in which an electrical charge experiences a force. The
direction of the electrical field at a point is the direction that a positive test charge would move when placed at that point.
3
Q
Electric field strength
A
The force per unit positive charge.
