Position vector of the mid-point of line segment {\AB} is 3 \stackrel{\^}{i}+2 \stackrel{\^}{j}-3 \stackrel{\^}{k}. If position vector of the point A is 2 \stackrel{\^}{i}+3 \stackrel{\^}{j}-4 \stackrel{\^}{k}, then position vector of the point {\B} is

Correct Answer is : 4i^+j^−2k^

\stackrel{\^}{5 { {\i}}}/{2}+ \stackrel{\^}{5 { {\j}}}/{2}- \stackrel{\^}{7 { {\k}}}/{2}

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

5 \stackrel{\^}{i}+5 \stackrel{\^}{j}-7 \stackrel{\^}{k}

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