Chapter 22, Problem 24E(choose chapter or problem)
CP A very small object with mass \(8.20 \times 10^{-9}\) kg and positive charge \(6.50 \times 10^{-9}\) C is projected directly toward a very large insulating sheet of positive charge that has uniform surface charge density \(5.90 \times 10^{-8} \mathrm{C} / \mathrm{m}^{2}\). The object is initially 0.400 m from the sheet. What initial speed must the object have in order for its closest distance of approach to the sheet to be 0.100 m?
