# If a, b, c are the position vectors of the points A, B, C respectively and 2a+3b−5c=0, then find the ratio in which the point C divides line segment AB. - Mathematics and Statistics

If bara, barb, bar c are the position vectors of the points A, B, C respectively and  2bara + 3barb - 5barc = 0 , then find the ratio in which the point C divides line segment  AB.

#### Solution

2bara + 3barb - 5barc = 0

5 barc=3barb+2bara

barc=(3barb+2bara)/5

barc=(3barb+2bara)/(3+2)

∴C divides seg AB internally in the ratio 3 : 2
