6. In the figure, which diagram represents the vector addition,C = A + B?
- A.
I
- B.
II
- C.
III
- D.
IV
Correct Answer
B. IIExplanation
Diagram II represents the vector addition C = A + B because it shows the two vectors A and B being added head-to-tail. The resulting vector C starts at the tail of A and ends at the head of B. This is the correct method of vector addition, where the magnitudes and directions of A and B are combined to determine the magnitude and direction of C.Rate this question:

7. In the figure, which diagram represents the vector addition,C = - A + B?
- A.
I
- B.
II
- C.
III
- D.
IV
Correct Answer
C. IIIExplanation
Diagram III represents the vector addition C = -A + B. In this diagram, vector A is shown in the opposite direction with a negative sign, and vector B is shown in the same direction. When we subtract vector A from vector B, we get vector C. Therefore, diagram III is the correct representation of the vector addition C = -A + B.Rate this question:

8. In the figure, which diagram represents the vector addition, C = A - B?
- A.
I
- B.
II
- C.
III
- D.
IV
Correct Answer
D. IVExplanation
Diagram IV represents the vector addition C = A - B because it shows the vector A pointing in one direction and the vector B pointing in the opposite direction. When we subtract vector B from vector A, we get vector C which is shown in Diagram IV. The other diagrams do not accurately represent the subtraction of vector B from vector A.Rate this question:

9. Which of the figures is not drawn head-to-tail?
- A.
I
- B.
II
- C.
III
- D.
IV
Correct Answer
A. IExplanation
Figure I is not drawn head-to-tail because the tail of the arrow does not connect to the head of the next arrow. The other figures (II, III, and IV) are all drawn head-to-tail, meaning that the tail of one arrow connects to the head of the next arrow in a continuous line.Rate this question:

8. In the figure above, which diagram represents the vector addition, C = A - B?
- A.
I
- B.
II
- C.
III
- D.
IV
Correct Answer
D. IVExplanation
Diagram IV represents the vector addition C = A - B. In this diagram, vector B is subtracted from vector A, resulting in vector C. The direction of vector C is determined by subtracting the direction of vector B from the direction of vector A. The magnitude of vector C is determined by subtracting the magnitude of vector B from the magnitude of vector A. Therefore, diagram IV correctly represents the vector addition C = A - B.Rate this question:
