Question

If $\hat{i}$, $\hat{j}$, $\hat{k}$ are right-handed orthogonal unit vectors, then $\hat{i} 	imes \hat{j}$ equals:

Accepted Answer

C. $\hat{k}$

By the right-hand rule for the cross product, $\hat{i} 	imes \hat{j} = \hat{k}$. The cyclic order i → j → k gives the positive sign.

Answer

$\hat{i}$

Answer

$\hat{j}$

Answer

$-\hat{k}$

If $\hat{i}$, $\hat{j}$, $\hat{k}$ are right-handed orthogonal unit vectors, then $\hat{i} \times \hat{j}$ equals:
