Potential EnergyHardQuestion 31460

Question

Electrostatic potential energy stored in an electric field E occupying volume V is:
  1. A
    ½ε₀E²V
    Correct
  2. B
    ε₀E²V
  3. C
    ½ε₀EV
  4. D
    ε₀E/V

Correct answer

½ε₀E²V

Explanation

Energy density = ½ε₀E². Total energy = ½ε₀E² × Volume (for uniform field). This is analogous to ½μ₀H² for magnetic energy density.
