Question
The quantity (1/2)εεE² has the significance of:
Correct Answer
Option D is the correct answer.
Detailed Explanation
The expression (1/2)εE² represents the energy density stored in an electric field. Energy density is defined as the amount of energy stored per unit volume. Here, ε (epsilon) is the permittivity of the medium and E is the electric field strength.
Hint
Recall the formula for energy stored in a capacitor and how it relates to electric field and volume.
