6.2 electric fields Flashcards
1
Q
what is an electric field
A
a region of space where any object with charge will experience a force
2
Q
state Coulombs law
A
the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
3
Q
relationship between electric force and seperation
A
inverse square law as F ∝ 1/r²
4
Q
define electric field strength, E
A
the force per unit charge on a positive charge placed at that point. E = F/Q
5
Q
unit for E
A
NC -¹
6
Q
magnitude of the electric field strength at any point in a uniform field formula
A
E = V/d
