In the figure shown there is a large sheet of charge of uniform surface charge density`'sigma'`.A charge particle of charge `'-q'` and mass `'m'` is projected from a point A on the sheet with a speed `'u'` with the angle of projection such that it lands at maximum distance from A on the sheet. Neglecting gravity, find the time flight
