Question

Vector B and C must lie in the plane of vector A and D if vector A and D are not collinear and in the line of vector A and D if they are collinear?​

Answer 1

Explanation:

(c) The magnitude of a can never be greater than the sum of the magnitudes of b, c, and d, (d) b + c must lie in the plane of a and d if a and d are not collinear, and in the line of a and d, if they are collinear? ... Hence, the magnitude of vector a can never be greater than the sum of the magnitudes of b, c, and d.
