1
Q
What does a charged object create around itself?
A
an electric field
2
Q
What is an electric field?
A
a region where a force acts on a charged particle
3
Q
Where is an electric field the strongest?
A
- the electric field is strongest closest to the charged object
4
Q
What does a second object placed in an electric field experience?
A
experiences a force - the force gets stronger as the distance between the objects decreases
5
Q
How must field lines be drawn?
A
must be at right angles to the surface
6
Q
Field lines on a positively charged object:
A
a positively charged object has field lines moving away from it
7
Q
Field lines on a negatively charged object:
A
a negative charged object has field lines moving towards it
8
Q
Where is an electric field weaker?
A
- the further away from the object, the weaker the field
9
Q
What happens when a second charged object is put in a field and where do the thing it experiences get stronger?
A
- a second charged object placed in an electric field experiences a force - the force gets stronger as the distance between the objects decreases
10
Q
What does how close together the field lines are show?
A
the closer together the field lines are the stronger the electric field
