Question

Let A and B be the two vectors of magnitude 10 unit each. If they are inclined to the X-axis at angles 30° and 60° respectively, find the resultant by component method.
Component method means by taking x and y components.

Answer 1

Explanation:

magnitude of vector A = magnitude of vector B = 10 unit. vector A inclined to the x - axis at angle 30° and vector B inclined to the x -axis at angle 60°. where indicates angle between vector A and vector B. hence, resultant = 10√(2 + √3) units.
