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

$6\hat i$

C

$7\hat k$

D

$3\hat i - 4\hat j$

Solution

(c) Force $F$ lie in the $x-y$ plane so a vector along $Z-$axis will be perpendicular to $F$.
