Answer:
Let mass of particle-1 is m1 and its coordinate (x1 , y1 , z1 )
 
Let mass of particle-2 is m2 and its coordinate (x2 , y2 , z2 )
 
X-coordinate of centre of mass, begin mathsize 12px style X space equals space fraction numerator m subscript 1 x subscript 1 space plus space m subscript 2 x subscript 2 over denominator m subscript 1 space plus space m subscript 2 end fraction end style   
Y-coordinate of centre of mass, begin mathsize 12px style Y space equals space fraction numerator m subscript 1 y subscript 1 space plus space m subscript 2 y subscript 2 over denominator m subscript 1 space plus space m subscript 2 end fraction end style  
Z-coordinate of centre of mass, begin mathsize 12px style Z space equals space fraction numerator m subscript 1 z subscript 1 space plus space m subscript 2 z subscript 2 over denominator m subscript 1 space plus space m subscript 2 end fraction end style
