Given that $\overrightarrow { \mathbf { A } } + \overrightarrow { \mathbf { B } } = x _ { 1 } \hat { \mathbf { i } } + y _ { 1 } \hat { \mathbf { j } }$ and $\overrightarrow { \mathbf { A } } - \overrightarrow { \mathbf { B } } = x _ { 2 } \hat { \mathbf { i } } + y _ { 2 } \hat { \mathbf { j } }$ ,what is $\vec { B }$ ?

• A) \[\overrightarrow { \mathbf { B } } = \frac { 1 } { 2 } \left( x _ { 1 } - x _ { 2 } \right) \hat { \mathbf { i } } + \frac { 1 } { 2 } \left( y _ { 1 } - y _ { 2 } \right) \hat { \mathbf { j } }\]
• B) \[\overrightarrow { \mathbf { B } } = \frac { 1 } { 2 } \left( x _ { 1 } + x _ { 2 } \right) \hat { \mathbf { i } } + \frac { 1 } { 2 } \left( y _ { 1 } - y _ { 2 } \right) \hat { \mathbf { j } }\]
• C) \(\overrightarrow { \mathbf { B } } = \frac { 1 } { 2 } \left( x _ { 1 } - x _ { 2 } \right) \hat { \mathbf { i } } + \frac { 1 } { 2 } \left( y _ { 1 } + y _ { 2 } \right) \hat { \mathbf { j } }\)
• D) \(\overrightarrow { \mathbf { B } } = \frac { 1 } { 2 } \left( x _ { 1 } + x _ { 2 } \right) \hat { \mathbf { i } } + \frac { 1 } { 2 } \left( y _ { 1 } + y _ { 2 } \right) \hat { \mathbf { j } }\)
• E) \(\overrightarrow { \mathbf { B } } = \frac { 1 } { 2 } \left( y _ { 1 } - y _ { 2 } \right) \hat { \mathbf { j } }\)
