A chlorine molecule with an initial velocity of 600 ms-1 absorbs a photon of wavelength 350 nm and is then dissociated into two chlorine atoms. One of the atoms is detected moving perpendicular to the initial direction of the molecule and having a velocity of 1600 ms-1. Calculate the binding energy of the molecule. [Neglect the momentum of the absorbed photon. The relative atomic mass of chlorine is 35.]
