We present an approximate solution around a global monopole resulting from a breaking of a global SO(3) symmetry in a five-dimensional space-time based on Lyra's geometry in normal gauge, i.e., displacement vector f_i = ( 0,0,0,0,b₀), where b₀ is a constant. Acceleration due to the monopole has been evaluated by studying the geodesic equation. A comparison is made with the classical results.
