Previous Year Question For Vector Algebra

If $\vec a\;\text{and }\vec b$ are unit vectors then the greatest value of $\sqrt3\left |\vec a+\vec b \right |+\left | \vec a\;-\vec b \right |$ is.
If $\overrightarrow{x}\; \text{and}\; \overrightarrow{y}$ be two non-zero vectors such that $\left | \overrightarrow{x}+\overrightarrow{y} \right |=\left |\overrightarrow{x} \right |$ and $2\overrightarrow{x}+\lambda \overrightarrow{y}$ is perpendicular to $\overrightarrow{y}$ , then the value of $\lambda$ is ________
Let $a,b,c\; \epsilon \; R$ be such that $a^{2}+b^{2}+c^{2}=1$ . If $a\cos \theta =b\cos \left ( \theta +\frac{2\pi }{3} \right )=c\cos \left ( \theta +\frac{4\pi }{3} \right ),$

Where $\theta =\frac{\pi }{9},$ then the angle between the vectors $a\hat{i}+b\hat{j}+c\hat{k}$ and $b\hat{i}+c\hat{j}+a\hat{k}$ is?
