An electric field of 1000 V m⁻¹ exists between two parallel plates 4 cm apart. The potential difference between them is:
A10 V
B25 V
C40 V
D100 V
Answer & Solution
Correct answer: C. 40 V
1. For a uniform field, V = E · d.
2. = 1000 V m⁻¹ × 0.04 m = 40 V.
3. The plate at higher V is on the side where the field arrow points FROM.
