Vector A is directed along the positive y-axis and has magnitude √(3.0) units. Vector B is directed along the negative y-axis and has has a magnitude 1.0 unit. What is the magnitude and direction of A + B?

Homework Answers

Answer #1

Given vector units in the positive y-axis and vector B= 1 in the negative y-axis. So the angle between the two vectors is .

Since the two vectors are opposite in direction, the direction of the resultant will be in the direction of the vector having larger magnitude. So the direction of is along positive y-axis.
