\begin{array} { l } { \text { The angle between vectors } \overline { \mathrm { A } } = 4 \hat { \mathrm { i } } + 3 \hat { \mathrm { j } } \text { and } } \\ { \overline { \mathrm { B } } = 3 \hat { \mathrm { i } } - 4 \hat { \mathrm { j } } \text { is } } \end{array} |

Answer» The dot product between A and B gives 12-12=0. Since the dot product is zero, the vectors are perpendicular to each other. Hence, angle between A and B is 90°. |
