5.3 Electric Fields Flashcards
1
Q
Define
Electric field
A
An electric field is a region in space where charged objects experience a force. This force can be attractive or repulsive.
2
Q
Define
Electric Field Strength
A
The force acting on unit positive charge.
3
Q
Equation
Electric Field Strength
A
E = F⁄q
4
Q
State
Coulomb’s Law
A
Each point charge will exert a force on another point charge which is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
