An infinitely large non-conducting plane of uniform surface charge density sigma has circular aperture of certain radius carved out from it. The electric field at a point which is at a distance 'a' from the centre of the aperture (perpendicular to the plane) is (sigma)/(2 sqrt(2) in_(0)) . Find the radius of aperture :

There is an infinite non conducting sheet of charge having uniform charge density sigma . The electric field at a point P at a distance x from the sheet is E_(0) . Point O is the foot of the perpendicular drawn from point P on the sheet. A circular portio of radius r lt lt x centered at O is removed from the sheet. Now the field at point P becomes E_(0)-DeltaE . Find DeltaE .
