Two flawlessly conducting spheres are in an evacuated region of space. One is at a potential of 12 volts as well as the other is at a potential of 15 volts. A free electron is released as of rest at the surface of the sphere at -12 volts. With what speed does it collide into the other sphere? (The mass of an electron is 9.11 × 10-31 kg.)
