A very small object with mass 7.50×10−9 kg and positive charge 7.30×10−9 C is projected directly toward a very large insulating sheet of positive charge that has uniform surface charge density 5.90×10−8C/m2. The object is initially 0.460 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?
