There are two vectors $\vec{A} = 6\hat{i} + 9\hat{j} - \hat{k}$ and $\vec{B} = 2\hat{i} + 3\hat{j} - p\hat{k}$ which have the same direction. The value of '$p$' is

$A$ vector $\vec{P}$ makes angles $\alpha, \beta,$ and $\gamma$ with the $X, Y,$ and $Z$ axes respectively. Then $\sin^2 \alpha + \sin^2 \beta + \sin^2 \gamma = $

If the angle between unit vectors $\hat{a}$ and $\hat{b}$ is $60^{\circ}$, which of the following vectors have a magnitude of $1$?
$(A)$ $\frac{\hat{a} + \hat{b}}{\sqrt{3}}$
$(B)$ $\hat{a} + \hat{b}$
$(C)$ $\hat{a}$
$(D)$ $\hat{b}$

Which of the following is a vector quantity?

$A$ particle has a displacement of $12 \, m$ towards east,$5 \, m$ towards north,and $6 \, m$ vertically upward. The magnitude of the resultant displacement is ......... $m$.

The angles which a vector $\hat{i} + \hat{j} + \sqrt{2} \hat{k}$ makes with $X, Y$ and $Z$ axes respectively are
