How the magnitude of vector quantity is represented ?
If a vector $\overrightarrow P $ making angles $\alpha, \beta\ and\ \gamma$ respectively with the $X, Y$ and $Z$ axes respectively. Then ${\sin ^2}\alpha + {\sin ^2}\beta + {\sin ^2}\gamma = $
Position of a particle in a rectangular-co-ordinate system is $(3, 2, 5)$. Then its position vector will be
