What does a steep slope on an electric potential graph suggest about the electric field?.
- A.The electric field is weak
- B.The electric field is strong
- C.The electric field is zero
- D.The electric field is variable
Model answer
What a good answer should say
- The electric field is strong
Explanation
Why this works
A steep slope on an electric potential graph indicates a large change in potential over a small distance, which corresponds to a strong electric field. This shows that a greater force would be exerted on a charge in that region, implying that the electric field strength is high.
Therefore, the conclusion is that a steep slope signifies a strong electric field.
