MCQ
The vector projection of a vector $3\hat i + 4\hat k$ on $Y-$axis is
  • A
    $5$
  • B
    $4$
  • C
    $3$
  • ✓
    $0$
✓

Answer

Correct option: D.
$0$
d
(d)As the multiple of $\hat j$ in the given vector is zero therefore this vector lies in $XZ$ plane and projection of this vector on $Y-$axis is zero.
