Question

Choose the correct alternative:
If `vec"a", vec"b", vec"c"` are the position vectors of three collinear points, then which of the following is true?

Options

• `vec"a" = vec"b" + vec"c"`

• `2vec"a" = vec"b" + vec"c"`

• `vec"b" = vec"c" + vec"a"`

• `4vec"a" + vec"b" + vec"c"` = 0

Answer 1

`2vec"a" = vec"b" + vec"c"`
