Question

Choose the correct alternative:
If ${\displaystyle \overrightarrow{\text{a}},\overrightarrow{\text{b}},\overrightarrow{\text{c}}}$ are the position vectors of three collinear points, then which of the following is true?

विकल्प

• ${\displaystyle \overrightarrow{\text{a}}=\overrightarrow{\text{b}}+\overrightarrow{\text{c}}}$

• ${\displaystyle 2\overrightarrow{\text{a}}=\overrightarrow{\text{b}}+\overrightarrow{\text{c}}}$

• ${\displaystyle \overrightarrow{\text{b}}=\overrightarrow{\text{c}}+\overrightarrow{\text{a}}}$

• ${\displaystyle 4\overrightarrow{\text{a}}+\overrightarrow{\text{b}}+\overrightarrow{\text{c}}}$ = 0

Answer 1

${\displaystyle 2\overrightarrow{\text{a}}=\overrightarrow{\text{b}}+\overrightarrow{\text{c}}}$
