Which of the following expressions are meaningful? |
$\vec u.(\vec v×\vec w)$ $(\vec u. \vec v).\vec w$ $(\vec u.\vec v)\vec w$ $\vec u×(\vec v.\vec w)$ |
$\vec u.(\vec v×\vec w)$ |
$\vec u.(\vec v ×\vec w)$ is also correct. Since $\vec u$ is a vector $\vec v ×\vec w$ is a vector as well as $\vec u.(\vec v ×\vec w)$ is feasible. |
