Multiple Choice

Find u × v and show that it is orthogonal to both u and v. $\begin{array} { l } \mathbf { u } = - \mathbf { i } + \mathbf { k } \\\mathbf { v } = \mathbf { j } - 3 \mathbf { k }\end{array}$

• A) \(\begin{array} { l }
• \mathbf { u } \times \mathbf { v } = \mathbf { i } - 3 \mathbf { j } - \mathbf { k } \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { u } = 0 \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { v } = 0
• \end{array}\)
• B) \(\begin{array} { l }
• \mathbf { u } \times \mathbf { v } = - \mathbf { i } - 3 \mathbf { j } - \mathbf { k } \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { u } = 0 \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { v } = 0
• \end{array}\)
• C) \(\begin{array} { l }
• \mathbf { u } \times \mathbf { v } = - \mathbf { i } + 3 \mathbf { j } - \mathbf { k } \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { u } = 0 \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { v } = 0
• \end{array}\)
• D) \(\begin{array} { l }
• \mathbf { u } \times \mathbf { v } = - \mathbf { i } - 3 \mathbf { j } + \mathbf { k } \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { u } = 0 \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { v } = 0
• \end{array}\)
• E) \(\begin{array} { l }
• \mathbf { u } \times \mathbf { v } = \mathbf { i } - 3 \mathbf { j } + \mathbf { k } \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { u } = 0 \\
• ( \mathbf { u } \times \mathbf { v } ) \cdot \mathbf { v } = 0
• \end{array}\)
