What does the slope of an electric potential graph represent?.
- A.Electric field strength
- B.Charge
- C.Work done
- D.Potential difference
Model answer
What a good answer should say
- Electric field strength
Explanation
Why this works
The slope of an electric potential graph indicates the electric field strength, as it represents the change in potential per unit distance. This shows how the electric field varies in space, implying that a steeper slope corresponds to a stronger electric field.
Therefore, the correct interpretation is that the slope directly relates to electric field strength.
