Write the distributive law for the product of two vectors.
Obtain the scalar product of two mutually perpendicular vectors.
Two vector $A$ and $B$ have equal magnitudes. Then the vector $\mathop A\limits^ \to + \mathop B\limits^ \to $ is perpendicular to
If $\overrightarrow P .\overrightarrow Q = PQ,$ then angle between $\overrightarrow P $and $\overrightarrow Q $ is ....... $^o$
Define the vector product of two vectors.
Dot product of two mutual perpendicular vector is
