SUMMARY
The discussion centers on calculating the electrical potential energy of two small metal spheres, A and B, each with a mass of 6.5 g and 12.7 g respectively, and both carrying a charge of 8 μC. The spheres are connected by a non-conducting string of length 1.4 m. To find the electrical potential energy, apply Coulomb's Law, which quantifies the force between charged objects. Additionally, upon cutting the string, the acceleration of each sphere can be determined using Newton's second law, factoring in their respective masses and the electrostatic force acting on them.
