If the position vectors of the points A and B are 2 \overline{i}+3 \overline{j}-\overline{k} and \overline{i}-\overline{j}+2 \overline{k} respectively, then the unit vector along \overline{ {\BA}} and in the direction of \overline{A B} is

Correct Answer is : 1√26(−i−4j+3k)

{1}/{\sqrt{14}}(3 \overline{ {\i}}+2 \overline{ {\j}}+\overline{ {\k}})

{1}/{\sqrt{26}}(-\overline{ {\i}}-4 \overline{ {\j}}+\overline{3 {\k}})

{1}/{\sqrt{26}}(-3 \overline{i}-4 \overline{ {\j}}+\overline{ {\k}})

{1}/{\sqrt{22}}(3 \overline{ {\i}}-4 \overline{ {\j}}+\overline{3 {\k}})
