Any vector in an arbitrary direction can always be replaced by two (or three)
Parallel vectors which have the original vector as their resultant
Mutually perpendicular vectors which have the original vector as their resultant
Arbitrary vectors which have the original vector as their resultant
It is not possible to resolve a vector
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 = $
A particle is moving with speed $6\,m/s$ along the direction of $\vec A = 2\hat i + 2\hat j - \hat k,$ then its velocity is
Angular momentum is
Surface area is
If a unit vector is represented by $0.5\hat i + 0.8\hat j + c\hat k$, then the value of ‘$c$’ is
