​

Answer 1

Answer:

Therefore (-i), (-j) & (-k) are the unit- vectors respectively along the negative direction of x, y, & z axes.

Answer 2

Answer:

You know that i, j, k are respectively the unit- vectors along the positive directions of x, y,& z axes of rectangular Co-ordinate system . Therefore (-i), (-j) & (-k) are the unit- vectors respectively along the negative direction of x, y, & z axes.
