List of top Physics Questions on Vectors asked in LPUNEST

If $\vec A + \vec B + \vec C = 0$, then $\vec A \times \vec B$ is equal to:
Vectors $\vec a$ and $\vec b$ include an angle $\theta$ between them. If $(\vec a+\vec b)$ and $(\vec a-\vec b)$ respectively subtend angles $\alpha$ and $\beta$ with $\vec a$, then $(\tan\alpha + \tan\beta)$ is:
