Peeling force for an electrostatically charged sheet on a grounded surface

The force required to peel a charged sheet from its underlying ground plane is successfully predicted using two computational models-one based on a discretized numerical simulation, and the other based on a simpler model in which the charged sheet is represented by horizontal and vertical rectangular charge distributions of uniform density. These two models both predict that the electrostatic attraction between a uniformly charged peeled sheet and its ground plane will be a linear function of peeling distance. This prediction has been verified experimentally. Contrary to intuition or expectations, the sheet contour at the separation point of the peeled cloth appears to be a near-perfect right angle, both experimentally and computationally. The electrostatic attraction between the peeled sheet and the ground plane is a long-range force involving the entire region of peeled sheet, and not just the electrostatic charge near the separation point
