What is the magnitude and direction of 2i + J vector

1.	What is the magnitude and direction of 2i + J vector
Answer» 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.
