Explanation Given information : The requiredvector is determined by the line of intersections of the planes x + y + z =3 and 2 x + 3 y − z =4 . Formula used : The line of intersections of two planes is determined bythe vector N 1 → × N 2 → , where N 1 → and N 2 → are vectors normal to the planes. The line of intersection of planes is parallel to the vector N 1 → × N 2 → . Calculations: The given planesare x + y + z =3 … (1) 2 x + 3 y − z =4 … (2) The vectors normal to the planes (1) and (2) are N 1 → =i+j+k , and N 2 → =2i+3j-k respectively. The vector perpendicular to both normals N 1 → and N 2 → is N 1 → × N 2 → = | i j k 1 1 1 2 3 -1 | =- 4i+3j+k
