Review motion of a neutral particle in the Reissner-Nordstrom space-time

در این مقاله به بررسی حركت یك ذره خنثی در اطراف سیاه چاله های باردار می پردازیم. ... In this paper we will review the motion of a neutral particle in a charged space-time .First, we me Schwarzschild solution to understand the concepts like singularity and event horizon in Kruskal coordinate. Then we consider the space-time diagram for the Reissner-Nordstrom space-time, which is a solution to Einstein equation describing a charged black hole, expressed Eddington- Finkelstein Coordinate. At the end, we study the behavior of a neutral particle by studying radial null geodesics in this space-time.
