On a clear day, there is a 100 V/m vertical electric field in the air near the Earth's surface. At the same time, the Earth's magnetic field has a magnitude of 50 micro T. Compute the energy contained in one cubic meter of air and compare it to the energy consumed by a person in one day of approximately 2,000 Cal (8.26 MJ)
