Vedclass · Answer

(c)

The vector perpendicular to the $i$ and $j$ plane would be along the unit vector $k$. Another vector in $i$ and $j$ plane can be perpendicular to $\overrightarrow{ F }$

$(3 \hat{i}+4 \hat{j}) \perp(4 \hat{i}-3 \hat{j})$

But, from the options only $7 \hat{ k } \perp(4 \hat{i}-3 \hat{ j })$

Consider a vector $F =4 \hat{ i }-3 \hat{ j }$. Another vector perpendicular of $F$ is
