According to me charge can be created (pair production) and destroyed (pair anhilation). Am i right?
Answers
Answer:
Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. For pair production to occur, the incoming energy of the photon must be above a threshold of at least the total rest mass energy of the two particles, and the situation must conserve both energy and momentum.
Answer:
Explanation:
Yes. An energetic photon (at least 1.022 MeV energy) can produce an electron-positron pair when travelling through an immensely changing electromagnetic field. These fields are typical at short distances from atoms.
Likewise, an electron can meet with a positron and annihilate into two photons.
There are many more examples in particle physics. However, you will find that every interaction that creates charge will create equal positive and negative amounts. And there are plenty of interactions that “destroy” charge into photons. But again, these too require equal positive and negative amounts.
