How is momentum conserved in pair annihilation, where an electron and a positron annihilate each other to produce gamma radiation?

Options

  1. AThe momentum is not conserved in this process.
  2. BThe momentum is conserved by the emission of an electron and a positron.
  3. C2γ photons are produced, moving in opposite directions to conserve momentum.
  4. DThe gamma radiation absorbs the excess momentum to maintain conservation.

Correct answer

C. 2γ photons are produced, moving in opposite directions to conserve momentum.

Step-by-step solution

Correct Option is : (C) 2γ photons are produced, moving in opposite directions to conserve momentum.
