Description

Our study investigates the gravitational field surrounding a charged, non-vacuum, non-rotating, spherically symmetric compact object with mass M and charge Q. Our investigation is based on a static solution to the Einstein-Maxwell field equations. We have shown the characteristics of perihelion precession within the orbits governed by the charged naked singularity spacetime. We uncover novel features of light-like geodesics in this unique gravitational environment. As well as this, we have conducted a comparative study of tidal forces in future null singularity, Schwarzschild, Reissner–Nordstrom, and charged naked singularity spacetime geometry. This comparative analysis provides valuable insights into the distinct gravitational effects associated with these singularities. By investigating these aspects, our research contributes to a deeper understanding of the gravitational dynamics surrounding charged naked singularities, shedding light on the impact of the charge on perihelion precession, light trajectories, and tidal forces. This investigation extends our comprehension of the interaction between gravity and electromagnetic fields in non-vacuum, spherically symmetric systems.
