Question

The resultant of two vectors will be minimum, if they are ______.

Options

• equal vectors

• parallel to each other

• coplanar vectors

• perpendicular to each other

Answer 1

The resultant of two vectors will be minimum, if they are equal vectors.

Explanation:

The resultant is minimum when two equal vectors act in exactly opposite directions (180° apart), giving R = A − A = 0, which is the smallest possible magnitude.
