Let and be the two vectors of magnitude 10 unit each. If they are inclined to the -axis at angles and respectively, find the resultant.Intuitive explanation
The key is to decompose each vector into its and components using the given angles, then add the components separately. Since both vectors have the same magnitude but point in different directions, their components will combine in a way that determines both the magnitude and direction of the resultant. Think of it as finding where two forces point when resolved along perpendicular axes—the final answer emerges from vector addition in component form.
