Question

Vector E is 0.111 units long in a 90.0° direction. In unit vector notation, this would be written as:

A. Ē = 0.111i^ + 0.111j^
B. Ē = 0.111i^ - 0.111j^
C. Ē = 0.111i^ + 0.111k^
D. Ē = 0.111j^ + 0.111k^

Answer 1

The vector E in unit vector notation is Ē = 0.111i^ + 0.111j^.

Step-by-step explanation:

To write the vector E in unit vector notation, we need to write the magnitudes and directions as components using the unit vectors i, j, and k. In this case, since E has a magnitude of 0.111 units and a direction of 90.0°, the unit vector notation would be written as Ē = 0.111i^ + 0.111j^, which corresponds to option A.
