Answer»
Column IColumn IIColumn III
\(\vec A. \vec B\)\(AB cos\theta\)\(\vec A. \vec B\) is a scalar quantity
\(\vec A \times \vec B\) AB sinθ \(\hat n\)Direction of \(\hat n\) is given by by right hand screw rule
\(\hat i. \hat i\)1\(\hat i\) is the unit of vector in the direction of X - axis
\(\vec r\) = x\(\hat i\) + y \(\hat j\)\(|\vec r|\) = \(\sqrt{x^2 + y^2}\) \(\vec r\) is a vector in two dimension
