A cubical region 1.0 m on a side is located between x=0 and x=1 m. The region contains an electric field whose magnitude varies with x but is independent of y and z: E=E0(x/x0), where E0 = 32 kV/m and x0 = 6.0 m . The answer needs to be in μ J.
Find the total energy in this region.
∫u * dV
The Attempt at a Solution
So I took the integral and got 1/2ε0(E0)(x/x0)^2. When I plug in the numbers I get 3.933 μJ which is wrong? Am I missing a step?
