Alevel Electric Fields Flashcards
1
Q
What is electric field strength?
A
Force per unit charge on a positive test charge placed at that point.
2
Q
What would happen if an electron was placed in the field?
A
Attracted to the positive, accelerate in opposite direction to the field lines.
3
Q
What is electric potential?
A
Work done per unit charge on a positive test charge when it is moved from infinity to that position.
4
Q
What is an electric field?
A
A region surrounding a charged object which causes a force to be exerted on any charged object placed within the field.
5
Q
What is Coulomb’s law?
A
Force between two point charges is proportional to product of charges and inversely proportional to square of distance between the charges.
