When we try to push a heavy box kept on ground, it does not move at all. Which force is preventing this box to move forward ? Where does this force act ?

A particle is placed on the top of a hemispherical shell of same mass. Shellis free to move on the smooth ground. If particle is given a given a gentle push and reaches to anglular position q as shown in figure then for an observer fixed on a shell, ratio of reaction force exerted by shell to peudo force (as observed from shell) acting on particale, is
