The line of intersection of the plane r (3 i - j + k ) = 1 and r ( i + 4 j - 2 k ) = 2 is parallel to the vector

MHT CET 2025 Mathematics question

The line of intersection of the plane and is parallel to the vector

Answer: (D)

The line of intersection is perpendicular to both normals, so it is parallel to $ × = = i(2 - 4) - j(-6 - 1) + k(12 + 1) = -2 i +
