A potential difference of 100 V is applied across parallel plates 0.02 m apart. What is the field strength between them?
Answer and explanation
Correct answer: C. 5000 V/m
- Step 1: In a uniform field . Step 2. V/m. Answer: 5000 V/m. Why not the others: 5 V/m treats 0.02 m as 20 m; 2 V m multiplies; 200 V/m is a decimal slip.
