Question

A uniform electric field within a parallel plate capacitor has field strength E = 4100 N/C. The plates are 0.5 m long, 0.001 m wide, and the space between the plates is 1.5 cm. What is the voltage difference across the capacitor?
Options
A 5.5 V
B 61.5 V
Correct Answer
C 0.615 V
D No option
Correct Answer

Option B is the correct answer.

Detailed Explanation

For a uniform field between parallel plates: V = E x d, where d is the PLATE SEPARATION (not the plate length or width). d = 1.5 cm = 0.015 m V = 4100 x 0.015 = 61.5 V. The plate dimensions (0.5 m and 0.001 m) are distractors - they are not needed here.

Hint

For a uniform field between parallel plates: V = E x d, where d is the PLATE SEPARATION (not the plate length or width).
