Reissner- Nordstrom metric- weak energy condition

[Lurian]

Hey,
For a problem I am working on I need to know if the energy-momentum tensor of the Reissner- Nordstrom metric obeys the weak energy condition. Since I need the result for the following calculations, I just want to be sure that it is correct. Does anyone of you know the correct answer and how to calculate it or an article concerning this topic?

Thank you

It's a vacuum solution.
