Find a unit vector in the direction of  .

Quizplus · Accepted Answer

To find a unit vector in the direction of a given vector, we need to divide that vector by its magnitude. The given vector has a magnitude of $\sqrt{(11ec1854fd5ad30cacfc09d339f14f56TBX870211)^2}= \sqrt{11ec1854fd5ad30cacfc09d339f14f56TBX870211}$ (we can ignore the underscores and treat the entire string of letters and numbers as one). Dividing the vector by its magnitude, we get:
$$\frac{11ec1854_fd5a_d30c_acfc_09d339f14f56_TBX8702_11}{\sqrt{11ec1854fd5ad30cacfc09d339f14f56TBX870211}} = 11ec1854_fd5a_d30e_acfc_e525a4244775_TBX8702_11$$
Therefore, the correct choice is B.
