Common transparent tape becomes charged when pulled from adispenser. If one piece is placed above another, the repulsiveforce can be great enough to support the top piece's weight.Assuming equal point charges (only an approximation), calculate themagnitude of the charge if electrostatic force is great enough tosupport the weight of a 17.4 mg piece of tape held 0.89 cm aboveanother. (The magnitude of this charge is consistent with what istypical of static electricity.)
