Final answer:
The potential energy of a particle with charge q due to other charges in a system can be determined using the formula based on Coulomb's law, which relates the charges and their separation distance. Changing the arrangement of charges in a system alters their potential energy. This concept is crucial in understanding electrostatic interactions and the conservation of energy.
Step-by-step explanation:
The potential energy of a particle with charge q due to other charges in a system can be calculated using the principles of electrostatics. For instance, the potential energy of two point charges can be found using a formula derived from Coulomb's law, which states that the potential energy between two point charges is proportional to the product of the charges and inversely proportional to the distance between them. This concept can be applied to a system of charges to find the overall potential energy, taking into account each pairwise interaction between charges.
Moreover, in a scenario where one of the point charges has a larger charge, like in the case with a charge Q, when this charge moves further away due to the Coulomb force, all the potential energy can be converted into kinetic energy, implying that potential energy and kinetic energy are easily transferable in electrostatic interactions.
Lastly, if we consider a system of three charges, the total potential energy of the system can vary if the positions of two charges are exchanged, such as trading places between a -2.00 µC charge and a 3.00 µC charge.
