The analytical solution of electron-acoustic solitary waves (EASWs) are reported for an unmagnetised quantum plasma model considering the effect of external periodic force. Using reduction perturbation technique (RPT) forced Korteweg-de-Vries equation is obtained. The effect of different physical parameters such quantum diffraction parameter (H), speed of travelling wave ($\lambda$), peak value of frequency f_0 and the frequency (w) of external periodic force are observed. This paper may be useful to the non linear features of EASWs in quantum plasma in the presence of external periodic force.
