The point which divides the join of (1,2) and(3,4) externally in the ratio 1:1 a. lies in the III quadrant          b. lies in the II quadrant           c. lies in the I quadrant            d. cannot be found

Explanation

The point which divides the join of `(1, 2)` and `(3, 4)` externally in the ratio` 1 : 1` is



`(1xx3−1xx1)/(1−1),(1xx4−1xx2)/(1−1)`


Which is not defined.


Therefore, it is not possible to externally divide the line joining two points in the ratio `1 : 1`
