Question

If a and b are the position vectors of A and B respectively, then the position vector of a point C on AB produced such that $Error converting from MathML to accessible text.$ is

$3 a - b$
$3 b - a$
$3 a - 2 b$
$3 b - 2 a$

The correct answer is: $3 b minus 2 a$

Since given that $Error converting from MathML to accessible text.$ It means that point $C$ divides $A B$ externally. Thus $Error converting from MathML to accessible text.$

Hence $Error converting from MathML to accessible text.$
