    The vector projection of a vector \[3\hat{i}+4\hat{k}\]on y-axis is:

    A)  5                                            

    B)  4

    C)  3                            

    D)         zero

    Correct Answer: D

    Solution :

    The vector projection of vector \[\vec{A}\] on \[y-\]axis is \[=\vec{A}.\,\vec{j}\] \[\therefore \]Vector projection \[=(3\hat{i}+4\hat{k}).\hat{j}\]                                 = 0
