An electron of mass \[{{m}_{e}}\] initially at rest moves through a certain distance in a uniform electric field in time \[{{t}_{1}}\]. A proton of mass \[{{m}_{p}}\] also initially at rest takes time \[{{t}_{2}}\] to move through an equal distance in this uniform electric field. Neglecting the effect of gravity, the ratio of \[{{t}_{2}}/{{t}_{1}}\] is nearly equal to                                                                  [IIT 1997 Cancelled]
