    this is one question with many parts, thanks for the help! A Imagine a negatively charged particle, A approaching another negatively charged particle, B, along the path shown in the diagram. A moves from point X to point Y. These two particles form an isolated system, which means no work is done by external forces; therefore, the system's total energy does not change. A foelsan clectrical force (an repelling force) from B while it approaches B. Therefore, work is done...
