Which of the following quantities is conserved in Pair production?
- Energy
- Momentum
- Electric Charge
- All of them
Explanation
In pair production, several quantities are conserved
Let's evaluate each option:
- Charge:
A charge is conserved in pair production, as the total charge before and after the interaction remains the same
Due to the opposite but equal charges of the electron and positron.
- Energy:
Energy is conserved in pair production, with the total energy before the interaction equal to the sum of the energies of the electron and positron after the interaction.
- Linear Momentum:
Linear momentum is conserved in pair production, with the total momentum before the interaction equal to the sum of the momenta of the particles involved.
