Find the Co-ordinates of the Point, Which Divides the Line Segment Joining the Points A(2, − 6, 8) and B(− 1, 3, − 4) Externally in the Ratio 1 : 3 - Mathematics and Statistics
Find the co-ordinates of the point, which divides the line segment joining the points A(2, − 6, 8) and B(− 1, 3, − 4) externally in the ratio 1 : 3.
Let `bara` and `barb` be the position vectors of the points A and B respectively.
Then, `bara = 2hati −6hatj + 8hatk` and `barb = −hati +3hatj −4hatk`
Let R( `barr` ) be the point which divides the line segment joining the points A and B externally in the ratio 1 : 3.
