MCQ
Consider a vector $\vec{F} \quad 4 \hat{i} 3 \hat{j}$. Another vector that is perpendicular to $\vec{F}$ is
  • A
    $4 \hat{i} \quad 3 \hat{j}$
  • B
    $6 \hat{i}$
  • ✓
    $7 \hat{k}$
  • D
    $3 \hat{i} \quad 4 \hat{j}$
✓

Answer

Correct option: C.
$7 \hat{k}$
(c) Force $F$ lie in the $x-y$ plane so a vector along $z$-axis will be perpendicular to $F$.
