P2 : Electric Fields

Question 1

What creates a force field

Answer 1

Non - contact forces, these forces do not need to be in physical contact for an interaction of forces to take place. Attraction / repulsion of static charges is an example of a non - contact force

Question 2

How do electric field lines work

Answer 2

Electric field lines flow away from positive charges and towards negative charges, the arrows show the direction a positive charge would move in the field

Question 3

What two things determine the strength of the field

Answer 3

Size of the charge
Distance away from the charge

Question 4

How is the strength of the field shown

Answer 4

The closer together the field lines, the stronger the electric field
