Dana Says Any Vector $\overrightarrow { \mathrm { R } }$

question 8

Multiple Choice

Dana says any vector $\overrightarrow { \mathrm { R } }$ can be represented as the sum of two vectors: $\overrightarrow { \mathbf { R } } = \overrightarrow { \mathrm { A } } + \overrightarrow { \mathrm { B } }$ .Ardis says any vector $\overrightarrow { \mathrm { R } }$ can be represented as the difference of two vectors: $\overrightarrow { \mathbf { R } } = \overrightarrow { \mathrm { A } } - \overrightarrow { \mathbf { B } }$ .Which one,if either,is correct?

• A)They are both wrong: every vector is unique.
• B)Dana is correct: Any vector can be represented as a sum of components and not as a difference.
• C)Ardis is correct: Any vector can be represented as a difference of vector components and not as a sum.
• D)They are both correct: A difference of vectors is a sum
• \(\overrightarrow { \mathbf { R } } = \overrightarrow { \mathbf { A } } + ( - \overrightarrow { \mathbf { B } } )\) .
• E)They are both wrong: Vectors can be moved as long as they keep the same magnitude and direction.
