A flat square sheet of charge (side 50 cm) carries a uniform surface charge density. An electrons0.5 cm form a point near the center of the sheet experiences a force of `1.8xx10^(-12)N` directed away from the sheet. Determine the total charge on the sheet.

If the uniform surface charge density on the infinite plane sheet is sigma , electric field near the surface will be

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
