Question

Bringing two like magnetic poles closer together, which requires effort, is an analogy for which electrostatic situation?

विकल्प

• Separating two opposite charges, which decreases the potential energy

• Moving a charge along a closed path, which has zero net work

• Bringing unlike charges together, which requires no work at all

• Bringing like charges closer, which requires external work that gets stored as energy in the system

Answer 1

Bringing two like magnetic poles closer requires effort. In a similar way, bringing like charges closer requires external work, which gets stored as energy in the system, illustrating the buildup of electrostatic potential energy.
