general relativity question.
Instructions The first problem is just a test of how well one knows the methods of averaging over directions. This is a standard tool which is used in many areas of classical electrodynamics and general relativity. e.g, in the context of the radiation problem and in the context of particle motion in inhomogeneous electromagnetic fields. The second problem is just a test of how well one understood the content of the present lecture. Solve the problems and...
