Question

According to Coulomb's law, which pair of charged particles has the lowest potential energy? a. a particle with a 1- charge separated by 150 pm from a particle with a 2+ charge, b. a particle with a 1- charge separated by 150 pm from a particle with a 1 + charge, c. a particle with a 1- charge separated by 100 pm from a particle with a 3+ charge

1 of 2

According to Coulomb's law, the relationship of the force between two charges is proportional to the number of charges and the distance between them. This indicates that between a positive and negative charge, the greater the distance creates greater potential energy. Given 3 different distances, we can see that letter c provides the nearest distance. Therefore, it creates the lowest potential energy.
