Abstract: In this paper, we provide the analytical expression of acceleration of neutral experimental particle in the gravitational field of black hole involving a global monopole and discuss the contribution of global monopole to acceleration effect. The results indicate that the repulsion effect takes place due to the global monopole, and when v c, neutral particle in the gravitational field is subjected to a repulsive force, which does not exist in Newtonian mechanics.
