A uniform electric field has the strength of 5.0 N/C.What is the electric energy density of the field? (The value of εo is 8.85 $\times$ 10 -12 C²/N·m². )

Question

Quizplus · Accepted Answer

The electric energy density of a uniform electric field is given by the equation u = (1/2)εoE^2, where εo is the permittivity of free space and E is the electric field strength. Plugging in the given values, we get u = (1/2)(8.85 x 10^-12 C^2/N·m^2)(5.0 N/C)^2 = 1.1 x 10^-10 J/m^3.
