An electron-positron pair approach each other with identical speeds. The particle-pair collide and annihilate, producing two photons with identical wavelengths of 1.9 picometres. Note: 1 picometre = 1 × 10^−12 m. (i) Calculate the energy of each of the photons produced.  (i) Calculate the speed of the electrons before the collision
