Answer 1
INCORRECT
If graph #1 was correct, then everything in the world would be electrified since it wouldn't make any difference the distance an object was from an electric field since the strength would be the same no matter what the difference. return to top
Answer 2
INCORRECT
It would be physically impossible for the electric field intensity to increase as the distance increased following a direct pattern.

Answer 3
CORRECT
As the distance increases, the intensity of the electric field decreases exponentially and eventually reaches a steady end. return to top
Answer 4
INCORRECT
It would not be physically possible for the electric field intensity to increase as the distance increased following exponential growth.
