An insulating sphere of radius 0.250 m has uniform charge density 7.40×10⁻⁹ C/m³. A small object that can be treated as a point charge is released from rest just outside the surface of the sphere. The small object has a positive charge 3.70×10⁻⁶ C.
How much work does the electric field of the sphere do on the object as the object moves to a point very far from the sphere?
