On a clear day at a certain location, a 106-V/m vertical electric field exists near the Earth's surface. At the same place, the Earth's magnetic field has a magnitude of 3.650 10-5 T.(a) Compute the energy density of the electric field. nJ/m3(b) Compute the energy density of the magnetic field. µJ/m3
