The two vectors $\vec A$ and $\vec B$ that are parallel to each other are
What is the product of two vectors if they are parallel or antiparallel ?
If $\overrightarrow P .\overrightarrow Q = PQ,$ then angle between $\overrightarrow P $and $\overrightarrow Q $ is ....... $^o$
The component of vector $A = 2\hat i + 3\hat j$ along the vector $\hat i + \hat j$is
