yes this is possible if the object is moving in a circuluar motoin , means centripetal acceleration , because force is in the circular motoin but the distance is perpendicular to the force , means make a cos90 angle , which is zero .... :) , ,. may be there is  also another way to explain but em not pretty sure

 yeah gotta remember may be object in equilibrium..
