Question 9

Electrostatics

Calculate the electric field intensity between two plates of potential difference 6.5V when separated by a distance of 35cm

  1. A.18.57NC−1
  2. B.53.06NC−1
  3. C.2.28NC−1
  4. D.0.80NC−1
Show the answer and explanation

Answer: A (18.57NC−1)

Explanation

E = V/d = 6.5 ÷ 0.35 = 18.57 N/C (or V/m).
