2. In a CH2.+ molecule of Fig. 2, three hydrogen (H) atoms form an equilateral triangle, with the center of the triangle at distance d = 9.40 x 10'11 m from each hydrogen atom. The carbon (C) atom is at the apex of a pyramid, with the three hydrogen atoms forming the base. Assume that the atomic mass of carbon and hydrogen is 12 and 1 respectively. The carbon-to-hydrogen distance L = 10.14 x 10'11m. What are the x and y coordinates of the molecule's center of mass? (12 marks)
