JEE Main & Advanced Physics Vectors Question Bank Fundamentals of Vectors

  • question_answer 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

    Correct Answer: B

    Solution :

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