What is the angle between $\overrightarrow P $ and the resultant of $(\overrightarrow P + \overrightarrow Q )$ and $(\overrightarrow P - \overrightarrow Q )$
What is the angle between $\overrightarrow P $ and the resultant of $(\overrightarrow P + \overrightarrow Q )$ and $(\overrightarrow P - \overrightarrow Q )$
Zero
${\tan ^{ - 1}}(P/Q)$
${\tan ^{ - 1}}(Q/P)$
${\tan ^{ - 1}}(P - Q)/(P + Q)$
What is the angle between $\overrightarrow P $ and the resultant of $(\overrightarrow P + \overrightarrow Q )$ and $(\overrightarrow P - \overrightarrow Q )$
Resultant $\vec R = \vec P + \vec Q + \vec P - \vec Q = 2\vec P$
The angle between $\vec P$ and $2\vec P$ is zero.
