Question

Vector $\overrightarrow{\text{A}}$ lies in xy plane and makes an angle will positive y direction. The x components of $\overrightarrow{\text{A}}$ is

• A. $A\cos \theta$
• B. $A\sin \theta$
• C. $A\tan \theta$
• D. $A\sec \theta$

Answer 1

The correct option is A $A\cos \theta$

$\left|\overrightarrow{A}\right|=A$
