MCQ
Consider a vector $\overrightarrow F = 4\hat i - 3\hat j.$ Another vector that is perpendicular to $\overrightarrow F $ is
- A$4\hat i + 3\hat j$
- B$6\hat i$
- ✓$7\hat k$
- D$3\hat i - 4\hat j$
✓
Answer
Correct option: C.
$7\hat k$
c
(c) Force $F$ lie in the $x-y$ plane so a vector along $Z-$axis will be perpendicular to $F$.
(c) Force $F$ lie in the $x-y$ plane so a vector along $Z-$axis will be perpendicular to $F$.
