Multiple Choice

Find a unit vector orthogonal to u and v. $\mathbf { u } = ( - 2 ) \mathbf { i } + ( 8 ) \mathbf { j } + ( - 1 ) \mathbf { k } \quad \mathbf { v } = ( 3 ) \mathbf { i } + ( 8 ) \mathbf { j } + ( - 1 ) \mathbf { k }$

• A) \(\frac { 1 } { \sqrt { 1625 } } ( ( - 5 ) \mathbf { i } + ( 0 ) \mathbf { j } + ( - 40 ) \mathbf { k } )\)
• B) \(45 ( ( 0 ) \mathbf { i } + ( - 5 ) \mathbf { j } + ( - 40 ) \mathbf { k } )\)
• C) \(1625 ( ( 0 ) \mathbf { i } + ( - 5 ) \mathbf { j } + ( - 40 ) \mathbf { k } )\)
• D) \(\frac { 1 } { \sqrt { 45 } } ( ( - 5 ) \mathbf { i } + ( 0 ) \mathbf { j } + ( - 40 ) \mathbf { k } )\)
• E) \(\frac { 1 } { \sqrt { 1625 } } ( ( 0 ) \mathbf { i } + ( - 5 ) \mathbf { j } + ( - 40 ) \mathbf { k } )\)
