A proton (mass: 1.67 * 10^-27 kg)is brought to within 1.0 pm of the center of a gold (Z = 79)nucleus,and released.How fast is it going when it is very far away from the gold nucleus?

Question

Quizplus · Accepted Answer

The speed of the proton when it is very far away from the gold nucleus can be found using the conservation of energy principle, specifically the conservation of mechanical energy. The initial potential energy due to the electrostatic force between the proton and the gold nucleus is converted into kinetic energy as the proton moves away. The correct calculation involves using Coulomb's law for the potential energy and equating it to the kinetic energy expression. The given options suggest that the calculation has been done and option A is identified as the correct speed, indicating the correct application of these principles.
