The electric energy stored per unit cubic meter is 7.5×10^(-8) joule/m³.
To find the answer, we need to know about the electric energy density.
In a vacuum where the permittivity is 8.85× 10^(-12), the electric energy density is 1/2 ×ε₀ ×E²
Energy density= (1/2)× 8.854×10^(-12)×130²
= 7.5×10^(-8) joule/m³
Thus, we can conclude that the energy density is 7.5×10^(-8) joule/m³.
