If \overrightarrow{p}=\stackrel{\^}{i}+\stackrel{\^}{j}, \overrightarrow{q}=4 \stackrel{\^}{k}-\stackrel{\^}{j} and \overrightarrow{r}=\stackrel{\^}{i}+\stackrel{\^}{k}, then the unit vector in the direction of 3 \overrightarrow{p}+\overrightarrow{q}-2 \overrightarrow{r} is

Correct Answer is : 13(^i+2^j+2^k)

\stackrel{\^}{i}+2 \stackrel{\^}{j}+2 \stackrel{\^}{k}

\frac{1}{3}(\stackrel{\^}{i}-2 \stackrel{\^}{j}+2 \stackrel{\^}{k}).

\frac{1}{3}(\stackrel{\^}{i}-2 \stackrel{\^}{j}-2 \stackrel{\^}{k})

\frac{1}{3}(\stackrel{\^}{i}+2 \stackrel{\^}{j}+2 \stackrel{\^}{k})
