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. The binding energy of the molecule is. [Neglect the momentum of the absorbed photon. The relative atomic mass of chlorine is 35]
(A) 3.36 × 10–17 J
(B) 3.36 × 10–19 J
(C) 3.36 × 10–21 J
(D) 3.36 × 10–28 J
