If the vectors \(\vec{a}=2\hat{i}-3\hat{j}\) and \(\vec{b}=4\hat{i}+3\hat{k}\) are given then the expression which is not defined as |
\(\vec{a}+\vec{b}\) \(\vec{a}\times \vec{b}\) \((\vec{a}\cdot \vec{b})\vec{a}\) \((\vec{a}\times \vec{b})\vec{a}\) |
\((\vec{a}\times \vec{b})\vec{a}\) |
Note that \((\vec{a}\times \vec{b})\vec{a}\) is not defined because\(\vec{a}\times \vec{b}\) is a vector which is perpendicular to \(\vec{a}\). |
