let electric field is along x axis .
and initial veloctiy of electron be v which makes and angle theta with x axis.
so initial velocity of electron along x axis v_x = v_cos theta ... and accelration along x is ,a = -eE / m .
at any time t let the electron be at (x,y )postion.
so x = ( v cos theta )t - 0.5 (eE/m ) t ^2 and y =( vsintheta)t.
so the path trace is an parabola.
