- Homework Statement:
- Relevant Equations:
I would like it very much if someone could give a hint on how to start this question.
In particular, I tried to find the derivative of energy with respect to time, but that was not enough.
Then I tried to apply the formula p * p = -m², but that also didn't get me anywhere.
These were my two attempts, I imagine there is another way but I haven't been able to find it yet
This is the metric:
The "magnetic charge" P is zero, at least i think so.
I thought in another way, try to find any Killing vector and see its relation with the energy, but i am not sure if this is will be helpful
