Abstract
In this paper,we study tidal forces in the Schwarzschild black hole,whose metric explicitly includes a generalized uncertainty principle(GUP)effect.We also investigate interesting features of the geodesic equations and tidal effects that are dependent on the GUP parameter αrelated to a minimum length.Then,by solving the geodesic deviation equations explicitly with appropriate boundary conditions,we show that α in the effective metric affects both the radial and angular components of the geodesic equation,particularly near the singularities.
