Find the vector and Cartesian equations of a plane containing the two lines \overrightarrow r  = (2\widehat i + \widehat j - 3\widehat k) + \lambda (\widehat i + 2\widehat j + 5\widehat k)and\overrightarrow r  = (3\widehat i + 3\widehat j + 2\widehat k) + \mu (3\widehat i - 2\widehat j + 5\widehat k). Also show that the lines \overrightarrow r  = (2\widehat i + 5\widehat j + 2\widehat k) + \rho (3\widehat i - 2\widehat j + 5\widehat k) lies in the plane.
