Let \overrightarrow{a}=\stackrel{\^}{i}+\stackrel{\^}{j}+2 \stackrel{\^}{k} and \overrightarrow{b}=\stackrel{\^}{i}-2 \stackrel{\^}{j}+3 \stackrel{\^}{k} be two vectors. Then the unit vector in the direction of \overrightarrow{a}-\overrightarrow{b} is

Correct Answer is : 1√10(3^j−^k)

{1}/{\sqrt{10}}(2 \stackrel{\^}{j}-3 \stackrel{\^}{k})

{1}/{\sqrt{10}}(3 \stackrel{\^}{j}-\stackrel{\^}{k})

(3 \stackrel{\^}{j}-\stackrel{\^}{k})

{1}/{\sqrt{5}}(2 \stackrel{\^}{j}-3 \stackrel{\^}{k})

{-1}/{\sqrt{5}}(2 \stackrel{\^}{j}-3 \stackrel{\^}{k})
