Q. An electron is at rest just above the surface of a sphere with the radius of 1.90 mm and a uniformly distributed positive charge of 2.1 x10-15 C. Like a rocket blasting off from the Earth, the electron is given an initial speed ve radially outward from the sphere. If the electron coasts to infinity, where its kinetic energy drops to zero, what is the escape speed, ve?
