Consider a particle with charge q in an static, homogeneous electric field. Using the fact that the net force on the particle in the surface integral of the Maxwell Stress Tensor, and assuming the surface is a sphere around this particle:

a) Find the net force on the particle (This part I can do)

b) Show that this approach can be applied even if the external magnetic field is not homogeneous and time dependent.


F[i] = Int (T[ij] S[i])

I am not really how to go about doing the second part. Do I break up the electric field into its vector components?

Thanks
