The Answer of Suppose $\vec { u } = 4 \vec { i } + b \vec { j } + 3 \vec { k }$ and $\vec { v } = a \vec { i } + 6 \vec { j } + 3 \vec { k }$ Find values for a and b making $\vec { u }$ perpendicular to both $\vec { v }$ and $\bar { j }$

Suppose u⃗=4i⃗+bj⃗+3k⃗\vec { u } = 4 \vec { i } + b \vec { j } + 3 \vec { k }u=4i+bj​+3k

Suppose $\vec { u } = 4 \vec { i } + b \vec { j } + 3 \vec { k }$
