For non-zero vectors $\vec{a}$ and $\vec{b}$, the relation $\vec{a}=m\vec{b}$ holds if and only if

Question

Accepted Answer

$\vec{a}\parallel\vec{b}$

Answer

$\vec{a}=\vec{b}$

Answer

$\vec{a}\perp\vec{b}$

Answer

$|\vec{a}|=|\vec{b}|$

For non-zero vectors a⃗\vec{a}a and b⃗\vec{b}b, the relation a⃗=mb⃗\vec{a}=m\vec{b}a=mb holds if and only if
