electric field Flashcards
1
Q
electric field
A
a region in which an electric force accts on a stationary charge placed at any point within the region
2
Q
coulomb’s law (formula for F)
A
the magnitude of electrostatic force between two point electric charges is directly proportional to the product of the magnitude of each charge, and inversely proportional to the square of the distance between the charges
3
Q
electric field strength at a point
A
electric force exerted per unit positive charge on a small stationary test charge placed at that point
4
Q
electric potential at a point (Φ)
A
work done per unit positive charge in bringing a small test charge from infinity to that point.
