A positron has the charge and mass of an electron except that the charge is positive. A positron that is initially at rest at a distance of 2.0 nm away from a stationary carbon nucleus is then allowed to move freely. What will be the speed of the positron when it is infinitely far away from the carbon nucleus? Since the carbon nucleus is much more massive than the positron, it remains at rest.
