Question

In nature, substances often possess a crystalline structure. The basic component of a crystal in the unit coil, such as the rectangular parallelepiped illustrated. In the questions that follow express your answers in terms of the unit vectors i, j, and k, that is, a vector with components V_r, V_s, and V_s in the x, y, and z directions, respectively. Is written V_s i + V_y j + V_a k. What is the vector V co from point C to point O? You did not open hints for this part. Answer V_co = What is the vector V OE from point O to point E? ANSWER. V_OE =

Answer 1

C is the point on the y-axis so its x- and z- components are zero.

The vector is given by

$V_{CO}=L_1\hat{j}$

The vector OE has positive x and z-components and no y-component

$V_{OE}=L_2\hat{i}+L_3\hat{k}$
