A photon converts into an ee -1 pair in a cloud chamber with magnetic field B =

Question:

A photon converts into an e→e^-1 pair in a cloud chamber with magnetic field B = 0.2 T. In this case, two tracks are observed with the same radius ρ = 20 cm. The initial angle between the tracks is zero. Find the energy of the photon.
