Find k for the given plane x + 2y + kz + 2 = 0 and directional ratios of a line (8, 3, 2), if they are parallel to each other.
Find k for the given plane x + 2y + kz + 2 = 0 and directional ratios of a line (8, 3, 2), if they are parallel to each other. Correct Answer -7
The condition for a plane and a line are parallel to each other is a1a + b1b + c1c = 0. 8(1) + 3(2) + 2(k) = 0 2(k) = -14 k = -7
