Answer» Solution :The coordinates of the centre of mass are `X_(CM) = (m_(1) x_(1) + m_(2) x_(2) + m_(3) x_(3))/(m_(1) + m_(2) + m_(3))= (m XX 1 + m xx 2 + m xx 3)/(m + m + m)` `Y_(CM) = (m_(1) y_(1) + m_(2) y_(2) + m_(3) y_(3))/(m_(1) + m_(2) + m_(3)) = ( m xx 1 + m xx 2 + m xx3)/(m + m + m) = 2` HENCE , the coordinates of centre of mass are (2,2)
