Two large parallel conducting plates are separated by a distance of 0.020 m in a vacuum. A potential difference of 200 V is applied between them. What is the strength of the uniform electric field between the plates?
Answer and explanation
Correct answer: B. 10,000 V/m
For a uniform electric field between parallel plates, the field strength is related to potential difference by E = V / d. Substituting values: E = 200 V / 0.020 m = 10,000 V/m (or 1.0 x 10^4 N/C).
