Question

what is the magnitude and direction of 2i + J vector ​

Answer 1

Explanation:

MAGNITUDE AND DIRECTION OF A VECTOR. Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application. For a position vector, the direction is found by tanθ=(ba)⇒θ=tan−1(ba), as illustrated in Figure 8.8.
