Question

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

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

Answer 1

Answer: (B)

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

Answer 2

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