Question 76

Multiple Choice

Two vectors lying in the xy plane are given by the equations A=5i^+2j^\overrightarrow { \mathbf { A } } = 5 \hat { \mathbf { i } } + 2 \hat { \mathbf { j } } and B=2i^3j^\overrightarrow { \mathbf { B } } = 2 \hat { \mathbf { i } } - 3 \hat { \mathbf { j } } .The value of A×B\overrightarrow { \mathbf { A } } \times \overrightarrow { \mathbf { B } } is
