Solution

The correct option is C $\to A B$
The vector is visual representation of a physical quantity that which has the both direction and the magnitude.
And out of these option,
Only option $B$ have the both direction and magnitude.
So, the correct answer is $\to A B$ .
Because it has a particular direction from $A$ to $B$ and also have the magnitude.

Q. Which of the following are meaningful
a)(u vector.v vector).w vector
b)u vector(v vector ×w vector)
c)u vector ×(v vector.w vector)

\to u

\to v

are unit vectors such that

\to u \times \to v + \to u = \to w

\to w \times \to u = \to v,

then the value of

[\to u, \to v, \to w]

\vec{u,} \vec{v} and \vec{w}

be vectors such

\vec{u} + \vec{v} + \vec{w} = \vec{0} .

|\vec{u}| = 3, |\vec{v}| = 4 and |\vec{w}| = 5,

\vec{u} \cdot \vec{v} + \vec{v} \cdot \vec{w} + \vec{w} \cdot \vec{u} .

\to u, \to v

\to w

are three non-coplanar vectors, then

(\to u + \to v - \to w) . (\to u - \to v) \times (\to v - \to w)
