The diagram depicts $\vec{v}$, $\vec{E}$ and $\vec{B}$, which are mutually perpendicular. If the direction of $\vec{E}$ is indicated with $\hat{j}$ and the direction of $\vec{B}$ is indicated with $\hat{k}$, then the direction of $\vec{v}$ is indicated as ....... The force value in each case is stated. State the value of $E$ and $B$ as equal to zero or not equal to zero in each case. $F = 0$ (if $|\vec{F}_e| = |\vec{F}_m|$ and their directions are opposite) if $E \neq 0$, $B$ ...... (choose $B = 0$ OR $B \neq 0$)
