Question

The position vector of the point (4, 5, 6) is

1. $4\vec{i}+5\vec{j}+6\vec{k}$
2. $4\vec{i}-5\vec{j}-6\vec{k}$
3. $2\vec{i}+\vec{j}+\vec{k}$
4. $\vec{i}+\vec{j}+\vec{k}$

Answer: $4\vec{i}+5\vec{j}+6\vec{k}$

Solution :-

The position vector of the point (4, 5, 6) is $4\vec{i}+5\vec{j}+6\vec{k}\mathrm{.}$

So, correct answer is option-2, $\to 4\vec{i}+5\vec{j}+6\vec{k}$
