A screened charge by a Yukawa potential implies that the correspondingelectric field is assimptotically zero far away from a small radius scaling.Considering a screened charge, we have a modified metric of typeYukawa-Reissner-Nordstr\"om spacetime, that assimptotically decays from aReissner-Nordstr\"om spacetime to a Schwarzschild spacetime. This implies thatthe singularity is screened by distance reducing from two singularities to onesingle singularity for a suitable distance. We consider the tetrad fieldsassociated to the Yukawa-Reissner-Nordstr\"om spacetime and show that a linearmotion in the proper time lead to suitable estimatives to the Yukawa screeningparameter associated to a Schwarzschild radius.
