A uniform electric field has the strength of $7.0 \mathrm {~N} / \mathrm { C }$ What is the electric energy density of this field? (?₀ = 8.85 × 10^-12C²/N ? m²)

Question

Quizplus · Accepted Answer

The electric energy density of a uniform electric field is given by the equation u = (1/2)ε₀E², where ε₀ is the permittivity of free space and E is the strength of the electric field. Substituting the given values into this equation, we get:u = (1/2)(8.85 × 10^-12 C²/N ? m²)(7.0 N/C)² = 2.2 × 10^-10 J/m³
