B) the law of conservation of momentum fails, despite accounting for field effects.
C) Both of the first two responses are valid.
D) Neither of the first two responses is valid.

Question

Quizplus · Accepted Answer

In certain situations involving magnetic forces, such as when dealing with electromagnetic fields and charged particles, Newton's Third Law may appear to fail because the forces are mediated by fields, which can carry momentum themselves. However, the overall conservation of momentum, including the momentum of the fields, still holds true.
