Define cross product of two vectors. If $\vec{a} = \hat{i} + 3\hat{j} + 4\hat{k}$ and $\vec{b} = 2\hat{i} + 7\hat{j} - 5\hat{k}$ , find the vector $\vec{a} \times \vec{b}$ and $\vec{b} \times \vec{a}$ . [5]

Define cross product of two vectors. If $\vec{a} = \hat{i} + 3\hat{j} + 4\hat{k}$ and $\vec{b} = 2\hat{i} + 7\hat{j} - 5\hat{k}$, find the vector $\vec{a} \times \vec{b}$ and $\vec{b} \times \vec{a}$. [5]

$\vec{a} = \hat{i} + 3\hat{j} + 4\hat{k} \quad\Rightarrow\quad (a1, a2, a3) = (1, 3, 4)$ $\vec{b} = 2\hat{i} + 7\hat{j} - 5\hat{k} \quad\Rightarrow\quad (b1, b2, b3) = (2, 7, -5)$ The cross product (vector product) of two vectors $\vec{a}$ and $\vec{b}$ is a vector perpendicular to the plane ...
