Find the position vector of the mid-point of the vector joining the points `P(2 hat i-3 hat j+4 hat k"")a n d"Q"(4 hat i+ hat j-2 hat k)dot`

Explanation

`P(2 \hat{i}-3 \hat{j}+4 \hat{k}) \quad Q(4 \hat{i}+\hat{j}-2 \hat{k})`


`\vec{R} =\frac{\vec{p}+\vec{q}}{2} `


`=\frac{(2 \hat{i}-3 \hat{j}+4 \hat{j}+(4 \hat{i}+\hat{j}+2 \hat{k})}{2} `


`=3 \hat{i}-\hat{j}+\hat{k} \hat{k} `
