GIven vector are $\overset{\to}{A} =$\left(2\overset{^}{i} + 3\overset{^}{j} - \overset{^}{k}\right)m$and$\overset{\to}{B} = \left(\overset{^}{i} + 2\overset{^}{j} + 2\overset{^}{k}\right)m$</p><p>Component of$\overset{\to}{A}$along$\overset{\to}{B} = \overset{\to}{A} \cdot \overset{^}{B}$</p><p>$= \dfrac{\overset{\to}{A} \cdot \overset{\to}{B}}{\left|\overset{\to}{B}\right|} = \dfrac{2 + 6 - 2}{\sqrt{{1}^{2} + {2}^{2} + {2}^{2}}}$$= \dfrac{6}{3} = 2
