question 137

Multiple Choice

• A)Vector \(\overrightarrow { \mathrm { A } }\) is parallel to vector \(\overrightarrow { \mathrm { B } }\) .
• B)Vector \(\overrightarrow { \mathrm { A } }\) is antiparallel (in the opposite direction)to vector \(\overrightarrow { \mathrm { B } }\) .
• C)Vector \(\overrightarrow { \mathrm { A } }\) must be perpendicular to vector \(\overrightarrow { \mathrm { B } }\) .
• D)The magnitude of vector \(\overrightarrow { \mathrm { A } }\) must be equal to the magnitude of vector \(\overrightarrow { \mathrm { B } }\) .
• E)The angle between vector \(\overrightarrow { \mathrm { A } }\) and vector \(\overrightarrow { \mathrm { B } }\) must be 90°.
