A `gamma`-ray photon is passing near a nucleus and breaks into an electron and positron. The region contains a uniform magnetic field B perpendicular to the plane of motion. Find the time after which they again converted into `gamma`-ray. The force of electrostatic interaction and gravitational interaction may be neglected
