What is the escape speed for an electron initially at rest on the surface of a sphere with a radius of 1.3 cm and a uniformly distributed charge of 2.3 ✕ 10−15 C. That is, what initial speed must the electron have to reach an infinite distance from the sphere and have zero kinetic energy when it gets there?
