    An electron is moving under the influence of the electric field of a uniformly charged infinite plane sheet SS having surface charge density +σ+\sigma. The electron at t=0t= 0 is at a distance of 1 m1\text{ }m from SS and has a speed of 1 m/s1\text{ }m/s. The maximum value of σ\sigma if the electron strikes SS at t=1 st = 1\text{ }s is α[mϵ0e]Cm2\alpha\left\lbrack \frac{m\epsilon_{0}}{e} \right\rbrack\frac{C}{m^{2}} the value of α\alpha is
