Question

Position of a particle in a rectangular-co-ordinate system is (3, 2, 5). Then its position vector will be

• A. $3 \hat { i } + 5 \hat { j } + 2 \hat { k }$
• B. $3 \hat { i } + 2 \hat { j } + 5 \hat { k }$
• C. $5 \hat { i } + 3 \hat { j } + 2 \hat { k }$
• D. None of these

Answer 1

Answer: (B)

$3 \hat { i } + 2 \hat { j } + 5 \hat { k }$

Answer 2

If a point have coordinate (x, y, z) then its position vector $\overrightarrow { O P } = x \hat { i } + y \hat { j } + z \hat { k }$
