Textbook Question

Chapter 21, Problem 78GP

When clothes are removed from a dryer, a 40-g sock is stuck to a sweater, even with the sock clinging to the sweater’s underside. Estimate the minimum attractive force between the sock and the sweater. Then estimate the minimum charge on the sock and the sweater. Assume the charging came entirely from the sock rubbing against the sweater so that they have equal and opposite charges, and approximate the sweater as a flat sheet of uniform charge.

Students have asked these similar questions

A 0,04 kg polystyrene ball Y, covered by a thin layer of graphit is positively charged and placed in a measuring cylinder. An identical neutral ball is dropped into the measuring cylinder. X makes contact with Y. X is now repelled upward so that the centres of X and Y are 0,03 m apart. Calculate the initial charge on Y.

If two identical conducting spheres are in contact, any excess charge will be evenly distributed between the two. Three identical metal spheres are labeled A, B, and C. Initially, A has 8 nC of charge, B has -4 nC of charge, and C is uncharged. What is the final charge on sphere A if C is touched to B, removed, and then C is touched to A? Note: Your answer is assumed to be reduced to the highest power possible.

A 0.01294 kg ball with a positive charge of 47.4 μC hangs from a light string right next to a large vertical metal plate (the metal plate is so large compared to the length of the string and ball consider it to be infinite in size). How much surface charge density must the plate have to repel the ball so that the string makes and angle of 5.03 degrees from the vertical. Give your answer to 3 significant figures and in units of nC/m/m (nanoCoulombs per meter squared: Blackboard has trouble with squred units). Type in the units right after your numerical answer.
