Question

Negative mutual potential energy corresponds to attraction between two charges

Answer 1

Negative mutual potential energy:

1. Negative potential energy may be defined as the work that must be done against the electric field in moving the distance of the charges apart.
2. This energy must be equal to the energy received at the receiver.
3. Hence a transmitter can't send any energy out without the receiver.
4. For two distant objects, the energy is transferred can by the mutual energy of a retarded potential from the source together with an advanced potential from the sink.
5. A liquid stays together because of attraction between its molecules.
6. Consider a single molecule well inside a liquid.
7. The intermolecular distances are of that type it is attracted towards all the surrounding molecules.
8. This type of attraction results in negative potential energy for the molecule

Thus, We can say Yes, Negative mutual potential energy corresponds to the attraction between two charges.
